This guy gets it. Best way to get humans to do something, is to tell them they can’t do it. I like yer style dude.

Having had the privilege of having him as a professor, very inspirational to hear him speak on this topic!

These are awesome ideas for steampunk sci-fi! Ships whizzing around the solar system, gathering speed for a journey and doing the opposite in the destination. Relativistic weaponry firing shots that seem absolutely ridiculous but catching the enemy on its next turn around a planet. I absolutely love how that kind of space travel resembles sailing more than modern rocketry.

I remember as a kid, I used to think stars were just little specs of light that you could touch in outer-space lol I remember the day in school that I found out that those specs were actually distant sun’s just like our sun but super far away & you could never touch them! I was mind blown 🤯 Even today when I explain to other people that don’t know about space that those specs of light you see in the sky are actually distant sun’s just like our sun! it’s always fun to see them be mind blown just as I was all those years ago ☀️💫🚀🌎

Andrew Higgins seems a really down-to-earth guy for wanting to go interstellar. Good to see that someone like Andrew Higgins is running the Interstellar Symposium.

Every time I hear about using the solar winds for interstellar travel I think about that Deep Space 9 episode (Explorers, Season 3, Ep. 22). Commander Sisko built a sailing ship based off of an ancient Bajoran design and achieved warp speed. I loved that show!

Good tp hear that Jeff Greason's talents are being utilized. Though we've lost touch, I always appreciated Jeff's intellect and vision.

Andrew Higgins needs to write a book for the general public. This is a really fascinating topic. I'd read it and it would likely inspire many people to pursue this goal.

I was supposed to be falling asleep to the sweet sounds of science, and when this talk got going I bolted wide awake and my imagination just went wild. What a gorgeous idea!! This is the most exciting thing I’ve heard since I first learned about the solar gravitational lens about a year ago. I cannot wait to see where this goes!!

Theoretical physicists are great but practical engineering is arguably more fascinating when discussing topics like this! Great convo!

watching this interview a year later and dropping a reminder we are closer to our nearest star today then when this interview posted 😂🤯

This guy is so endearing and honest. I'v paraphrased but - "what a beautiful thought to tread lightly on Earth, industry doesnt happen here any more " "Yeah we COULD do it that way but we must think of this, this and this" Really easy to understand, thoroughly enjoyed this video, gonna go check your other stuff now, subscribed!

Testing those technologies in the solar system is very important in my opinion. The jump from chemical rockets to interstelar travel is huge. It would also be important to draw attention and funding to those projects.

In all the years I’ve been watching science content on UKposts this is by far the most exciting one ever. I was glued to this interview from start to finish and am now trying to figure out if I can get to Montreal for the symposium. Thank you so much!

I’m about a year late watching this. I’m really liking this guest. Explanations about the solar winds were easier to understand than I had previously thought. Thank you. Also I’d like to hear more about the coils that were mentioned.

Catching up on all the space news and stories. Loved this interview...even though most of it blasted over my head at 10% the speed of light. Thanks Fraser for another great interview

This interview was speechless this man has so much information that he just threw on to all of us that it just blows my mind. I had no idea that birds can sense that in the wind and there was an actual application for using it with a glider. This changes everything and I really hope that the people that are in this field working on this live a long life so they can give us as much knowledge as possible for us to go into interstellar space. Thank you so much for this interview

That was a fun interview. It makes me wish I were immortal to see what kind of technologies and discoveries are going to happen long after I would've died.

This is such a great interview. Mr. Higgins is a great teacher!

Dreams are there to inspire us. They don't have to be practical or realistic, they can just be fantastic dreams.

You are a dream killer Fraser, but you're also a dream creator because when you put down a person that is really driven to get something to work, they will someday get it done, one way or another.

There is a 1 billionth scale model of the Solar System along the Melbourne foreshores with a 1.4m diameter Sun centred in St Kilda, a 12.5mm Earth 150m away and Pluto 5.8km away near Port Melbourne. When you walk the distance between 140mm Jupiter and 116mm Saturn (assuming they actually were in alignment, which they mostly aren't) you truly appreciate just how much nothing there is in space. I missed it the first time I was there, but a 215mm Proxima Centauri is near the Sun in this scale, based on having travelled the entire circumference of the Earth to reach it. The scale you mention of the Sun being the size of a grapefruit, the Earth would be much smaller than a peppercorn.

Amazing talk thank you very much! So glad I subbed to this channel. Future generations are going to witness these Interstellar missions and they are in for a real treat! I'm glad the rest of us are around to see the first small steps taken!

OMG! I know Joe Jackson! I used to work in the residential A/V feild out of a suite RIGHT NEXT DOOR to H-Bar Technologies, and actually got to tour their facility after asking him "Doesn't it require 'dammit' magnetic containment to store antimatter?", to which he responded "No, nothing nearly as extreme as you might imagine." He then showed me around and even showed me the containment vessels (two DIFFERENT types) which were only approximately the size of a large home deep freezer. Just thouht I'd share...

One of the most powerful things in the universe, is the drive and passion of a human being when their mind is working.

We need a lot more interviews like this!

I would *love* it if we went back to Neptune in my lifetime! I've loved Neptune since I was a kid - a long time ago - and even wrote a short sci-fi story about Neptune in middle school. Really enjoyed this conversation!

That anti matter factory would be interesting. Would have to be built in the middle of nowhere. Kilograms of anti matter and matter going up in an accident would be quite a headache Ahh, 13:00, Andrew said to build it in space, yes, that would be wise

Fantastic interview! Thanks. It's great to know we have people like Andrew Higgins right here at McGill.

0:01 _"I feel like I am a dream killer"_ Heck yeah! Back then I showed up on the channel, and started dreaming of visiting a place with such lush vegetation as Fraser's backgrounds, only to later learn it's just very advanced green screen CGI! ( ;-;)

What an awesome guest! He really spoke in Layman's terms so a schlep like me could understand. Great stuff. Extremely informative.

1:00:48 "tread lightly". Beautifully spoken.

Fascinating interview, thanks Frasier! Imagine getting up to 20 - 30% without a Jupiter massed quantity of negative energy! Didn't think I was going to watch the entire thing when I started it due to the length, but once he started talking I was hooked.

Great Interview! I've always been a fan for the solar wind ;-) and for a second age of sail, looking forward to it, Thank you Fraser and Andrew.

This was the interview that got me into following this channel a year ago

thanks for this; I've been intrigued a lot with dynamos, electromagnetism (and how euclidean paths can separate electrical currents from base magnetism), plasma, and even chemistry (trapped within our Gravity-well) including electronegativity and figuring out how to--if not reverse--prevent the apparent entropy it's subjected to. this talk rly is a 'breath' of fresh 'air' (medium)

Best video of the year. Thank you Fraser you have given us something to get excited about.

one of the most insightful and informative interviews I've heard in a long time. thanks

This was the video that ultimately urged me to pursue my dream of studying physics, now I start my journey next week. It was content like Fraser's that has kept my flame stoked through the rain. Thank you for this great interview and the months of inspiration I've received from your many videos.

New topic for John: Dynamic soaring. THANK YOU! I see applications in particle acceleration. I see applications in plasma control. I see applications in 30 story building air flow processes. I see thermodynamic applications akin to sonic refrigeration. You have just given me months of things to think about. I will never get any work done.

Love these interviews! So informative and captivating. Thanks to both of you 🙏😃

If we could achieve 2% of the speed of light in the solar system means that we could get to Pluto in 10 days! I had to do the calculation in Wolfram alpha, before the end of the episode, so I have no idea if they address this in the video

Could you imagine if we find a way to harness these space winds and our spacecraft ends up finding a super advanced civilization, which then sees our bunk ass ship sailing through space?

>Scientists have discovered magnetosheath jets, fast plasma streams, in Jupiter's magnetic environment New article in nature I saw and remembered this video, seems like there's a difference in energy that could be exploited there for the techniques mentioned in this video also mentions similar jets could be around other planets. I love the idea of Jupiter not just being the go-to planet for gravity assists but also plasma assists for either acceleration or deceleration with a plasma magnet/q-drive/e-sail, such a convenient planet lol

The Robert L. Forward book Rocheworld is still one of my favorites where a large laser in the Lagrange point behind Mercury and harnessing the power of the Sun - I forget the exact details - is used to power a large light sail propelling a large exploration vehicle. The sail is designed to break in segments part way through the journey with the outer sections being blown ahead of the craft where they then focus the laser from Earth back to the sail on the craft decelerating it for arrival at Barnard's Star. One question I do have is how do we protect sensitive components and eventually people for long range high speed travel through interstellar space. GCRs are likely a real threat to astronauts at even interplanetary ranges and at relativistic speeds the thin interstellar medium becomes high energy particles constantly bombarding the spacecraft. The faster you go the worse this becomes.

Fascinating conversation! Thank you for making this happen

All we need to do is reach 10% lightspeed. We could send the first manned mission to Proxima Centauri. It would be a 40-50 year journey, but it's possible to get there within a single lifetime. I think that's the most realistic goal at this point. The other possibility is sending a sleeper ship or generational colony ship which could possibly take hundreds of years to reach its destination. But trying to build a vessel that could survive for that length of time is also highly questionable and risky. And you'd also have to know there's a habitable planet before you send the mission.

I have always dreamt about space travel myself but now that I'm approaching 60 I've finally realized that it's a pretty good idea to stay here for me. I've also been telling dreamers the sobering facts about the challenges with space travel. They weren't happy. This video was great. I'm about to listen again. I'm not sure if you asked about the risk associated with colliding with some dust particle when traveling at insane speeds. Do we know the probability distribution for dust particles of various sizes in interstellar space? If we did we could calculate a probability distribution for arriving at the star as swiss cheese or as a cloud of atoms. Or still be alive.

That was extremely interesting! I listen to Astronomy Cast all the time (still trying to catch up from the very start - in the 200's now!) so I was glad that UKposts randomly threw this video my way!! A great discussion!

Great interview! That symposium will be quite interesting, can't wait to hear about it. Fraser will be busy :)

I've always been a bigger fan of "hard" sci-fi, namely the kind that focuses on fusion drives and only ever mentions warp drives as "theoretical curiosities" that we haven't ever achieved. So this is a welcome breath of fresh air. So tired of the "aliens" having the FTL tech and gifting it to us. So tired of us discovering how "easy" it is to go FTL ourselves. It trivializes the true difficulty of all things space travel, and in so doing it loses a lot of it's punch. There's some part of me that says "NASA and the like are purpose-oriented to tackle the most technically challenging areas of engineering we have yet faced, allowing a human to exist in an environment that has never encountered a being like them". And the rest of me goes "That's just a hair's breadth distant from being literally impossible, so why are all these sci-fi media depicting it being as easy as driving to the grocery store?" The story shouldn't be "XYZ plot, but in space". The story should be "Space, period." Unfortunately, nobody seems to be interested in writing that kind of sci-fi, it all seems to be in books written in the 40's to the -60's, with only a few select authors. More of it is needed IMO. Few example plots I can think of, just because there's oh-so-many ways for your ship to betray you in the most insidious of lethal ways: Life support systems fail on you? Better hope the whole crew's not in hibernation, or that the automated systems can wake up enough engineers to patch it together enough to get you to a safe place, else you're gonna have an encounter with The Cold Equations. Engines malfunction? Probably not gonna have the tools or materials to fix that, if it's a nuclear engine you better cut the failed one loose, and you better also have brought a spare (you're not gonna repair the magnetic bottle on your fusion drive if it got a railgun round shot thru the containment field coils cryo plumbing, and not JUST because it's "lethal in mere seconds" radioactive). By the way, you can't just say "oh it's not radioactive because it's using D-He3 fusion which is aneutronic", because even a D-He3 reactor is only "a lot less" radioactive, not "not radioactive", you're still doing high energy atomic physics, meaning D-D fusion is gonna be happening in that reactor in side-reactions, which emits even more neutrons than D-He3 fusion. The only reason it's "Less" neutronic is because those D-D side reactions are side reactions and not the main focus, so they don't happen nearly as often. Still plenty of them to cause the reactor itself to saturate any kind of radiation detector you care to point at it, with the drive turned off for 30 days and THEN measured. Colony run short on supplies, like needing a water pipe? Use lasers to 3-d print a stone or concrete water pipe out of local regolith, because if you use a pipe from anywhere remotely near the ship's power reactor or nuclear engines, the whole colony is gonna be fighting any number of "new and interesting" cancers. You thought Radium Jaw was bad, what do you think happens when the very water you drink and bathe with has been turned radioactive by a wrongly-selected piece of plumbing? Oh and it's not just pipes, valves and fittings are bad news too. So is something as mundane as an O-ring. Literally any matter that has been irradiated should be banned from contact with the potable water, ventilation, sanitation, or any other system that helps support the crew. Yes, that includes the sewer pipes, because you're almost certainly going to be recycling the wastewater from those systems. Alien contatct? Nope, no sentients, microbes at best. Alternately, if you do think we can contact sentients, it will be them contacting us, and us stumbling on to their transmissions as noise with strangely self-consistent patterns in it. Extremely extremely faint signals, we'd need at the MINIMUM a radio telescope on the Moon's far side to even have a chance of intercepting the signals so sent. The signal we sent, intentionally, probably didn't even make it to Alpha Cent, distance wise. That's how faint things get over such large distances. If you want a truly interesting set-piece, maybe us humans figure out that a pulsar isn't quite as perfectly regular as it should be in it's timing, instead it's somehow modulated. And then thru years of analysis using the most powerful supercomputers, we figure out that there is data encoded in this modulation. More years of analysis and we can figure out what that data is, if it's even digital data (who knows, they might develop computers based on "neuron" analogue cell-type constructions rather than doped semiconductors, depends on how easy it is to purify elements without resorting to what passes for biology on their world). Point is, expect it to look like "oddly patterned noise" for 5+ generations of analysis before we figure out what it is. Also expect some new religion to pop up to worship whatever it is they think it is we found when we actually still don't have a clue. Really really drive home the point of how so much of actual new territory being explored by science is best described as "fumbling around in the dark inside a house", but the only data you have is the theory of what a house is, namely something like "a house is composed of a series of connected rooms sharing a roofing system, with one or more floors, passage between floors being facilitated by stairs, ladders, or elevators". And we don't know what rooms, roofs, floors, passages, stairs, ladders, or elevators are yet either. Basically sometimes science is just flailing around in the dark and noting down what you bump into or knock over, and if you knock something over noting what noise it made when it fell.

Professor Higgins (OMG, that brings to mind "My Fair Lady") is full of extraordinary ideas! Great interview, Frazer!

Wow, this was fascinating! Thanks so much, you two

Real privilege to hear this man . Surprised he had the spare time . His brains so big it’s cauterised his hair cells. Excellent vid

one of the coolest physics videos I have seen in a long time!

This was a great conversation. I enjoyed it immensely 👍👍👍

This topic always gets my attention, thank you. Listening now!

My interest in the last decade has been in nuclear power and molten salt reactors specifically. The initial interest was in slow spectrum molten salt reactors using a fluoride/lithium/beryllium salt modeled on the Oak Ridge Molten Salt Reactor Experiment which ran for four year in the 1960s. Recent interest has shifted to fast spectrum molten salt reactors that use chloride salts which are safer, have better understood chemistry and are much cheaper. Sodium chloride is table salt. The advantage of fast spectrum reactors is at over 1 MeV U-238 and Th-232 become weakly fissile and add to the neutron budget. These reactors will run on spent nuclear fuel and plutonium from decommissioned weapons. They can also include depleted uranium as part of the fuel cycle. All this means there are very large stockpiles of fuel for these reactors currently being stored at considerable cost as high level waste. This could be the ample energy source needed to power an anti-matter production facility. Also molten salt reactors run much hotter than water moderated and cooled nuclear reactors making them far more practical for use in space. A cold water source is not needed to produce the thermal efficiency to draw the required amount of heat out of the reactor core. A molten salt reactor on a spaceship or a Moon base would use radiator fins for cooling. Hook one of these up to a Hall thruster and you have a much more efficient way to accelerate at least at interplanetary distances.

Amazing interview reach of proposals for the future 👍🏼 happy for that

Maybe an interesting thought: I wonder if there is a way to collect mass as one performs gravitational assists and solar wind turns that would allow for increasing one's kinetic energy without, as it were, gaining velocity and thereby running out of solar system? That is, in stage 1 of your sailing trip, you intentionally slow yourself by grabbing stuff (gas, whatever) as you perform these maneuvers and then once you reach a certain level of mass, you start stage 2, stop accumulating mass, and accelerate up to some crazy speed, then in stage 3, you take advantage of the energy of your accumulated mass and extreme speeds via Q-drive ideas by shooting your accumulated mass out the back.... Great video in any case! Really enjoyed it.

I Admire You Very Much! I appreciate the Fact You’re To the Point and Realistic ❤❤

I just watched a video of one of the dynamic soaring gliders they spoke about, and saw speeds in excess of 500mph.

I absolutely love Andrew Higgins' enthusiasm!

Excellent content. Thanks for this. I will watch this again.

Leia: "Would it help if I got out and pushed?" Han: "...It might!!"

Asking all the right questions thank you so much!

Every barrier we have encountered, or will encounter,has a will be overcome. Dream's in the past are now reality today. As will be in the future.

There are so many problems with this concept that I don't even know where to start. Recommended procedure for anyone: 1/ Buy KSP 2/ See and understand the orbital mechanics of the bodies 3/ Understand that it's already complicated to reach an inclination >20° in solar orbit 4/ Understand that it's impossible to stay in solar orbit as soon as the speed of the spacecraft exceeds 60km/s at 1UA. 5/ Understand that surfing on solar wind waves necessarily implies being able to detect the solar wind gradient around the spacecraft continuously. 6/ Understand that surfing on solar wind waves necessarily implies having an unimaginable TWR and therefore materials that resist. 7/ Understand that the solar liberation velocity at the heliopause is so low that it's insane to believe that we can stay in solar orbit down to even 0.05% of c. 8/ Stop believing in a whole bunch of far-fetched solutions and honour the engineers of the last 200 years by understanding that if they haven't already done it, it's because it's not possible. If this concept is feasible in the next 150 years, I'll eat my hat!

First, I am struck with how much I love Professor Higgins' bookshelf (but would hate to dust it as often as I would need to, were it here on this gravel road where I live, LOL!). And then I was able to pay attention to what he was saying, after I got done ogling the bookshelf. Just had to back it up to actually listen. 😄 The concepts he shared with us are quite fascinating! They could truly be used to send some kind of probes waaaay out there, and send back TONS of new information! A like and comment for the care and feeding of the Almighty Algorithm. ❤️ ❤️

I'm glad we don't have to wait for a warp drive to be invented to get a closeup look at exoplanets! I don't think I'll live to 2050 to see a probe launched to Alpha C, but my son almost certainly will and that blows my mind.

Just got around to watching this. Fascinating stuff thanks Frasier!

Money spent on this endeavor will reap untold advancements in our daily lives. Hats off to the professor who can make a difficult to understand subject understandable to those of us lucky enough to hear him speak. Thanks to Professor Higginsber, and Fraser Cain for tuning me in.

Bow shocks of planetary magnetic fields. You might be able to accelerate a cubesat out of the Earth-Moon system using this and interacting with Earth's magnetic shock of solar wind.

Not so much this negative energy esoteric Space - Time propulsion. But down to Earth hands on approach with these systems. Way to go🚀👍

Questions: What would happen to a craft traveling at 2% of the speed of light if it collided with a particle the size of a grain of sand? What would be the probability of that collision happening?

Unlike many commenters below who seemingly take all ideas total literally and then bash them... I really enjoyed the tossing of ideas around. I enjoy the process of speculation and thinking outside of the box.

Absolutely riveting segment, Fraser. Andrew is quite a visionary. Gives me hope. As always, thanks much for sharing. Steve

So much great information here! Love the space travel and energy talk.

I know this video is old, but this has to be said. Our species needs more people like you and the scientists you interview. As a civilization we need to rekindle our interests in exploring beyond the walls we have set for ourselves else we will stagnate. You and others have settled into the roles that the giants of Bill Nye and Carl Sagan have done before you, and I hope that you do for others what they have done for me. For us to succeed as a species we need to turn our gaze starwards as any alternative will never be as bright.

The closest known black hole is either V Puppis (960 ly) or HR 6819 (1,000 ly). I proposel that we build an O'Neill Cylinder with an anti-matter drive to go there. This is a generation starship that use the black hole to slow it done and enter orbit about the black hole. We talking a journey of about 5,000-10,000 years or more at 20% of c. The mission to start a base to build Halo Drive starships as proposed by Kipper, "Fuel-free Relativistic Propulsion of Large Masses via Recycled Boomerang Photons". This will open select parts of the galaxy, hopping from black hole to black hole. The bad news, to get back to Earth is HARD - maybe we could launch a Halo Drive starship with just enough moment to reach Earth and Bussard ramjet for breaking. Starting with 10,000 people in the first O'Neill starship, they will have descendants throughout the galaxy that will far out number the population of the Solar System in about 50,000 short years or so. STRONG DREAM REIGN HERE.

That dynamic soaring thing is super impressive. There is a video of it on UKposts.

At around 18:00 he's talking about dynamic gliding, and I think that's done in the book 7 Eves.

There is also nuclear pulse engines, you build a shield behind the craft you want to accelerate thick enough to withstand multiple nuclear blasts and launch a nuke behind the shield and explode it, repeat it with around 1000 nukes, and you can accelerate to near 20% the speed of light, turn the craft around and repeat the process to slow down at your destination

I always go back to Q's line in the STNG series. When confronted with how to move a falling moon he suggested that they "just change the Gravitational constant of the universe". Obviously, we need to get a whole lot smarter and need to push physics forward by orders of magnitude, but it seems much more possible to bend the universe than it does to try and build a "faster" spaceship.

It’s so exciting to see what might be possible! I’ve always been convinced it’s impossible and that I would never see it in my lifetime. Here’s hoping! 🤞🏻 thank you for the detailed explanations! 😸

35:19. The ship's cargo should be at the back in a bay area as in a cargo bay door emergency air pressure release. 💭

What isn't possible today becomes possible tomorrow. Not every idea comes to fruition, but when our understanding gets an update, problems can crumble away.

Very good Fraser. I would very much like to continue to see your skepticism and sharp logic. For example, let me say about the question and the possibility of our species and the desire and longing for the stars: Regarding the antimatter drive: - In 1996 some PICOGRAM anti-hydrogen atoms were successfully produced at CERN in Geneva for a few NANOSECONDS. Andrew Higgins speaks of a few kilograms of it for a very, very long travel time. What quantitative progress is there from 1996 to 2023? To the sun sails: - Tiny solar sails have hardly any capable control mechanisms, far-reaching communication options and complex orientation apparatuses integrated into them. Although some tiny life forms on Earth seem to be able to do it with brains of 0.025 mm2. The mayflies.

Wow Andrew said something that chimes with me and that was "I'm a little bored with our solar system" LOL As an astrophotographer I am often asked oh did you take pictures of the moon? Do you have pictures of Mars. I am like um no... I have this galaxy I would like to show you! Yeah the "System" we can come back to after we go into the deep end. Even if we hit the outer belts, still more interesting 🙂 Awesome interview! I now have to work on eating and exercising again to make sure I am alive when it finally happens LOL

Worthy content. Gladly liked and shared.

this is an absolutely mind blowing idea. i really hope some test vehicles can be quickly funded to start exploring this. its this sort of smarts that'll be the answer to our inability to come up with high density energy sources or advanced propulsion engines.

😮Fraser you did it! this is Jaw Dropping science the Dynamic Soaring Gliders are revolutionary ( 😊 )

Best qualifications for getting into interstellar propulsion? Basic pyhsics and sailing!

This is a video I keep coming back to. I don't know why I'm not hearing more about this 6 months later.

Fraser reminds me of a younger Richard Dreyfuss. On a serious note, one thing I am curious about is assuming that this plasma field thing did work and some sort of vessel could ride the solar winds, then how would someone identify the difference between a region of space that had reduced solar wind activity, to a region of space that had an increased level of solar wind activity? Therefore allowing the pilot to make the necessary adjustments in flight trajectory. (Flight may not be the right word to use in this case)

Amazing talk :)

Sailing ships have used the difference in speed between water and air to go faster then either for a very long time. In the past year or so the 'downwind faster than the wind' concept went somewhat viral on youtube. This was a ground vehicle with a large propeller coupled to the wheels, extracting energy from the speed difference and going faster than the wind. The idea of grabbing onto differences in solar wind speeds to extract energy is simply mindblowing. -Jon

Andrew Higgins thanks for sharing your thoughts this was a wonderful interview. 🤘🇦🇺🌌

I think that would be a great way to explore our solar system ... once we can make it work safely. There's a lot places that would be great if we could explore .. especially if we could get there fairly quickly.

Side note: I just watched that video of a glider using dynamic soaring, and it is freaking impressive... and a little bit scary. The whole time I'm like, "How is this thing not ripping itself apart?" because it's going so fast. I'd hate to be one of the spectators if that thing ever went out of control. ukposts.info/have/v-deo/bJV3eJWOoWyVyZ8.html
