The guys in this video are fantastic.

After watching this, I'm even more amazed by the dedicated teams that ensure these helicopters are always ready to swoop in and make a difference in critical situations

17 years of experience with a bunch of acronyms that he knows better than the words they stand for, and Destin just keeps asking what they stand for 😂

The humility and respect that rescue swimmer PO1 John Calhoun has for his counterpart aviation maintenance tech PO1 James Hockenberry is awesome. We often think of USCG rescue swimmers as the elite, bad a$$ dudes who put it all on the line to save people (which they do!). But John's deference to the guy who keeps the chopper flying is a testament to the camaraderie these teams have. I have no doubt the warrants/officers who fly the bird would speak highly of the enlisted men and women who serve with them.

Man, I really love watching professionals talk about their field. The guys in this video are fantastic.

It is very reassuring to watch how quickly Mr. Hockenberry swaps into safety procedures when turning the blades, talking about hazards around him or simply communicating with other officers about things that are happening live. It's like they've this second brain that's ready to override whatever they're doing to ensure the safety of others.

When we did preventive maintenance in the Navy, we were "taking it apart to see why it's still working."

I love Destin's humility both in acknowledging when he's ignorant on a topic and also when he's geeking out and namedropping all he knows (which is fun to see, actually). I love hearing all the different things that came up. You're a great and empathetic teacher, Destin! Thank you!

27:01 You see the guy's passion for his crew. His eyes and demeanor change immediately when he talks about his crew aka second family. You see that almost all the time in the aviation field, military or civilian. Something that's just magical. "Take care of your crew and they'll take care of you." Thank you for your service.

The mechanic explained it so well! Easy to understand

I genuinely love the fact that he is so invested to explain and show everything. It shows that they choose someone that is loving the fact that he can teach someone just for explaining purposes

I love how he gives a heads up before turning the blades. Such kind of small precautions really demonstrate the dedication to safety and professionalism.

My dad was an avionics guy for his whole career. So I grew up in hangers like this one. I am so appreciative of this video. Both of y'all nerding out is the conversation I needed today. Thanks for helping me get smarter today :). If you ever get a chance to get the behind-the-scenes of how NDT works for testing aircraft, that world be super interesting :)

Haha. "It's French, so it's opposite..." That's the standard pilot/co-pilot configuration for helicopters. Really impressed by the AMT's knowledge level of his platform.

As a former Coastie and Flight Mech on the MH-65, these videos really make me miss it. I'm surprised how much I remember about that aircraft, and every inspection we would do. Best job I've ever had... with some of the best people in the business.

I feel like Hockenberry has the most complete understanding of his subject matter than anyone else you’ve featured.

Can never get tired of listening to people who are so passionate about their respective field, and when they are able to share their knowledge in said area.

This man is so dedicated he is still making videos 16 years later, I respect the dedication

Man, I've really been enjoying this Coast Guard series. Everyone you've had in the videos has been incredibly cool, kind, passionate, and knew their stuff. Super inspirational.

I love Destin's humility when he names what he knows. And can teach other people.

As an old Coastie, I really appreciate those guys n gals. I’ve been able to visit a few stations n find them all so accommodating. Awesome people! Semper Paratus!!!

As a manufacturing engineer, I am very excited about this series.

1 year in the USCG as a non rate now thanks to your first SAR video! Hopefully will be an AET soon. Thanks for the great content over the years!

I’m in awe of the Coast Guard rescue helicopter teams. They go out in the worst conditions. As a former Army helicopter pilot, I respect the crew chiefs. Fortunately they always went on the missions with us.

I love just how intelligent and passionate the mechanics and engineers you talk to are. It's such a contagious energy that really makes me smile.

Awesome video. Loved the part at 28:10 where AMT Hockenberry finds something on the deck and appears unsure of what it is. It's amazing that they're able to so expertly and precisely maintain those incredible aircraft. As an avid recreational boater I'm grateful for their professionalism and thorough training and applaud their bravery and service.

This reminds me of my days working on aircraft in the USAF. Much respect to these guys. There is a ton of technical knowledge needed just to keep the guys that are flying it safe.

I love how they have a dedicated safety callout every time they move the blades even the slightest bit. It pays to have flawless safety habits. It may not look like it pays for a long, long time, but when it pays, boy does it pay.

I ship out in October. Hoping to go AMT or AET. Thank you, Destin, for hyping me up even more.

The way these guys are talking about there job and the level of enthusiasm is just incredible and inspiring to watch!!

I was an Aircraft Structural Mechanic who worked on helicopters (including Marine One) while in the Marine Corps. And I have to say that these Coasties really know their stuff! I'd fly with them any day. Thanks for the great video. And thanks to these professional, dedicated Coasties!

I like how safety has become like a muscle memory to them. When he shouted "Heads Turning" and quickly looked around to make sure no one was in the tail blades or head blades even though he was deeply focused on the topic.

Love this series, one of the best on youtube

I think it's good that you showed your knowledge at the start. I feel that's important to people who are explaining something so they know how much they have to dumb things down compared to talking to other experts in the field.

The hoist controls were one of the things I programmed while I was working on maintenance training software; I was working on the UH-60, but it has a rescue hoist that can be installed (which I also made work). Our model didn't animate the cable spooling out at the time, but we still had the digital readout display functioning. There's also some clever bits that prevent over-extending the line or over-retracting it. The last 50 feet or so can't be extended without an override switch (otherwise there wouldn't be enough left on the spool to reel back in properly) and the speed of extension or retraction automatically slows down to 10 feet/s when nearing both limits, to avoid a hard-stop.

Destin, to give context to the issue of corrosion and why all aircraft must be inspected for it, corrosion was one of the elements that caused part of the fuselage of Aloha Flight 243 to rip apart back in 1988. With that aircraft it was a combination of structural rivets corroding and failing, the adhesive that Boeing used at the time on the skin and tear strips failing due to salt water, and confusion about basing structural inspections on flight hours over number of compression/decompression cycles. The issue with corrosion of the rivets on Aloha 243 was that it would cause the rivets to fail, and as the body expanded and contracted from the pressure cycles of the flights, the rivets were creating microfractures in the skin and sheer strips. Then the compression/decompression caused those microfractures to expand until the skin failed. When the skin failed and tore, the sheer strips were too badly damaged to stop the tearing in the manner they were designed. Now, he's talking about corrosion with the airframe itself, but the issue is the same. If a structural support fails, forces involved in keeping the aircraft in the air will rip that helicopter apart in a similar manner as what happened to Aloha 243. ANY CORROSION IS BAD NEWS FOR AN AIRCRAFT. If they find any, they must ground the aircraft until the damage can be repaired as dictated by either the US Coast Guard and/or the FAA. (It's a "Whatever policy is more stringent" setting situation.) And, depending on where the corrosion is and how bad it is, the airframe could be permanently grounded. Also, if they do the repairs incorrectly, that can also ground the aircraft. China Airlines Flight 611 was a Boeing 747-200 that crashed because of an improperly installed patch over some damage to it's tail when the aircraft from the tail striking the runway (tail strike incident) more than twenty years before the incident in 2002. The incorrectly installed patch allowed the airframe to flex and bend in a way that metal fatigue happened, similar to the Aloha Flight 243. (Except that Aloha's issue was from missing important inspections and a few notices from Boeing, and not incorrect maintenance work performed for an existing repair.)

Hi, gyroscopic procession is not the reason for the advanced cycilc input, it's called aerodynamic procession. It just takes time for the blade to fly to it's new position. Aerodynamic procession fights against gyroscopic procession, that's why the rotor slows down when a cyclic input is made, energy transfer.

This might just be my favorite video of this channel. The way that my brain was just figuring out out how everything was made to address a specific matter (and solve/avoid problems that way) as all of you were discussing each aspect of the vehicle+its operation was utterly fabulous. Thank you.

Having your own mechanic onboard. That is great.

Reepicheep's words of wisdom at the end really fit the theme of this video really well.

Never apologise for your name dropping, it’s just your excitement over the experience beaming through; it’s one of the reasons I love your content. The excitement in the way you’re navigating a new learning experience inspires me. Thank you Destin

Just recently got my A and P license and my first job as an AMT. This video was awesome Destin. Really scratched that aviation itch and gave me a level of mechanical understanding to aspire to.

Terrific video. I was a Contracting Officer on the acquisition of the Dolphin, and I am amazed that some of them still had the original Rockwell Collins avionics suite at the time of Destin’s filming. Heck, I’m amazed they are still flying; aircraft tail number 6511 was delivered to USCG in 1985! CGNR 6511 and 6607 (seen in background at 6:39) have completed conversion to MH-65E configuration, with upgraded avionics (glass cockpit and radar) and are now stationed at Coast Guard Air Station Atlantic City, NJ. A further Service Life Extension Program will extend the service life the H-65 by 10,000 flights hours, enabling fleet operations until the planned phase out in fiscal years 2035-2039. Based on current programmed usage, the 10,000-flight hour extension per aircraft will provide a 50% increase in service life, or approximately 16 years.

I love watching masters of a craft talk about their craft. Destin, you are a master of asking the right questions to show off someone’s knowledge and teach your audience at the same time, well done.

So so good. Really nice to learn that the ones going on calls, are the ones maintaining it too, really fantastic job. Thank you Destin, and to all the lads that were so interested in showing us this, and for the job you guys do, legends.

This is what my dad did in the Coast Guard, in New Orleans. Can't wait to see the next installment!

CG for 20+ years here. Thank you Smarter Every Day for profiling the service and all we do. I’ve been up in the 65 a handful of times and these air crews are no joke. Bravo Zulu on a great video!

As an Army vet, my entire thoughts on the coast guard have been changed. Amazing people there and you can tell they have the utmost discipline and camaraderie.

Wow 17 years! It shows... he really does know his stuff tho! Love the mutual respect and admiration these guys all have for each other. Amazing team.

Imagine someone coming to your job and being over the top excited about every detail of what you do for a living ..

I was an auto pilot/instrumentation tech on the F4-E fighter. We used the red hydraulic fluid pressurized to 3000psi. You need that pressure to move the flight surfaces past mach 1. Great video.

One of my favourite things is Dustin always being INTERESTED and the technical people always happy to be INTERESTING.

As an AMT myself I’m really glad that you consulted this great group of fellow AMTs to learn about this awesome Aircraft. People don’t know enough about the profession and have no clue that pilots actually depend heavily on us AMTs or else they don’t get fly safely.

I love listening to two people who absolutely love the topic they are discussing. Great video and I love this series, can't wait for the next one!

My favorite episode yet!!! As a former Air Force helicopter crew chief, this brought back so many memories.

Really looking forward to the next episode!! Always admired the Coast Guard and always wanted to become a Helicopter Pilot for the Coast Guard when I was younger (unfortunately I’m not a US citizen) Got major respect for these guys they are actual heros!!

The mechanic explained it so well! Easy to understand. The mechanic explained it so well! Easy to understand.

I'm working on getting my AMT license here in PH, i really admire this AMT guy, he really knows the heli inside and out! great guy

Many Thanks to all you guys/gals in the Coast Guard ! You do an awesome job !!

I’m glad when I heard him say they follow CRM (Crew Resource Management). I only mention that because I know it’s operated much like the military based on rank/position so it’s nice to see that everyone onboard the Helicopter has a voice and encouraged to speak up. As a firefighter there is no other way to work because like they said they are your brothers and sisters and you want to make sure everyone makes it home and during ops so many things are going on no single person sees everything so you have to rely on your team and your team really does become your family. Thank you to the Coast Guard SAR Teams (Guardian Angels) for what you do and the sacrifices you make to bring those in need back home. GOD Bless!

The mechanic explained it so well! Easy to understand. The guys in this video are fantastic..

I dont really care for helicopters but man I always love seeing someone so excited to tell people about anything

I've always been a huge fan of helicopters. This is going to be an exciting series. Thank you Destin.

Hockenberry's enthusiasm is just phenomenal!

Those AC units are an absolute godsend. Anyone that works in a tight, hot, environment loves those things like their own mother.

Finally people on the subreddit can stop asking when the next Coast Guard video comes out lol. Thanks for the great content Destin, keep up the hard work!

2:33 good old H515 that gives you cancer...

meeting someone with the same passion, is always the best.

Sensational video! Thank you for such an in-depth look at the Dolphin and the crew that operate it. I’m a rescue swimmer operating out of a EC135 and I try to explain all the technical details to my kids. You nailed it so well. I look forward to watching your other videos with my boys.

When I first learned about the role gyroscopic precession plays in the main rotor system of a helicopter, it blew my mind. That the cyclic actuators for going forwards and rearwards are at the sides, and the ones for tilting the main rotor sideways are fore and aft. It was such an epiphany.

Destin, never apologise for getting excited over nerdy engineering stuff … it’s what we love to see the most!

Such an awesome awesomness! Helicopters are fantastic, and your story about this helicopter is a pleasure to watch!

The respect the flight mechanic has for his pilot is enorm! He, the pilot, makes the last call and they trust him to make the right one! Thank you for your service, what a blessing to see a little bit of behind the scenes. God bless.

What a phenomenal episode! Cannot wait for the next one. Thank you Destin!

Hey Destin, looking back on your older helicopter videos. I noticed a topic, "counter-toque side-slip" that you had intended to cover but never actually did (unless I'm mistaken). I really think it's worth a revisit. I recently published a guide for building helicopters for a game (kerbal space program) and had to discover the solution myself. Turns out, there's a lot of complex interactions, much more than it would initially seem and the rotor and tail are a lot more intricately linked, than I'm sure most people realise. My guide is on the official Kerbal Space Program forums for anyone that's interested. Simple called: Helicopter Build Guide.

The copter this is related to (the Panther) is also badass! Great video as always and mad respect to these brave CG personnel who save so many lives.

17:05 "If you're standing and hoisting...I wouldn't advise reaching up like that." 😂

Love this series, Destin. Thank you so much for letting us see a bit of the Coastie life!

Another great video. I have found the Coast Guard series very interesting as I grew up in Duluth, MN on the western tip of Lake Superior and there is a Coast Guard Station there. They do a lot of ice breaking in the Spring to open the shipping routes. I'm definitely looking forward to the next video in the Coast Guard series.

Don't feel ashamed about geeking out over the helicopter. The enthusiasm makes it more fun!

Credit to those mechanics, asking them pilot-related questions and they crushed it!!!

Can you ask about their liquid lighting egress system? And their 5point harnesses? I have a feeling you’ll be very intrigued by them! I helped design them in high school!

This always happens to me when I see some of your videos or engage in a conversation with someone very passionate about what they do, and is that, I can barely keep up with the amount of information but when I can digest it I feel way more educated.

I love how universal the phrase "secret squirrel stuff" is.

I wish our maintenance shop was that clean. What a dream

16:28 Man, Jowers' spatial awareness is incredible.

Heavy D Sparks will love the Dolphin helicopter episode 🚁

Work: "Why aren't you getting ready?" Me: "Five more minutes"

Absolutely blew my mind when they talked about secondary hoist. You don't want to leave anybody behind. Heroes go to work everyday with that mentality. I work in Emergency Services, and I love my job, but I've never once gone to work thinking one of my guys wouldn't make it home that night, no matter what I do or say. These guys do think that, every single day. Thanks, Destin, for showing us what these heroes do Every day! Braver Everyday!

These deep dives don't just feed your brain, they trigger the fast-twitch curiosity muscle, heat the emotional heart and if you watch them all, you'll be Destined to get Smarter Every Day.

That ceiling fan looked interesting :3 Also it's astonishing how much maintenance have to be done per hour of flight.

One day I hope to be as knowledgeable in my job as these guys are in theirs.

I was hoping you checked out the nose and radar of the bird. I wonder if it's powerful enough to pick out boats in open seas or if it's just for weather observation.

24:44 not because it's french.. all choppers have the captain on the right ;)

Destin, you are one of my favorite YTubers, and you are doing a deep dive into my favorite flying machine of all time, the USCG HH-65. My biggest regret in life is not pursuing a career with the USCG. They have come to my assistance in the Gulf of Mexico twice, and as far as I am concerned, the last legitimate practitioners and teachers of proper seamanship in North or South America. What an out standing look at an outstanding group of professionals. My admiration for the Coast Guard knows no bounds, and I am ashamed I made no real effort to join their ranks when I was a young man. To all those who have made the USCG their profession and family, cheers! Thanks for doing what you do. I know it's an under-appreciated job, but those of us that are drawn to the sea, we know you, we see you, we respect you, and we love you.

It’s young men like these Coast Guard Technicians that give me hope our country will survive. Respect. Thanks.

Last christmas I got the Airbus rescue helicopter lego set for Christmas. And building it gave me a lot of appreciation to how complicated the mechanics of helicopters are. When I rotated the rotors and saw the tail start spinning too, I was mind blown.

I was watching the older coast guard videos last week wondering when this was coming!!

3:00 I love your humility; in spite of knowing so much, you know what you don’t know. That’s important.
