And I'm amazed they haven't replaced parts prone to corrosion with parts that aren't.

[@newmonengineering]

​@Mmouse_ salt water corroded most things with enough time. You can replace some things but it depends on what engineering requirements are for the part. You can't just replace stainless steel with carbon fiber, there are many aspects of the parts like strength, weight , flexibility, hardness etc that need to be considered. Many parts are aluminum and steel, but some can be replaced, others would never work because of the stresses involves. Unfortunately every boat, and aircraft have parts that corrosion eats over time. It just needs to be on the inspection checklist and replaced when needed. That's why a regular maintenance schedule is mandatory per FAA regulations. It would be awesome if someone can develop something that matches the criteria to replace with something that does not corrode but we are not there yet.

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.

@@jaredgrubb30 I presumed OSHA would be everywhere but I suppose you have other systems in place to hold you accountable. Gotta imagine there's still some stuff in the military that goes under the radar but most of the incidents I've heard about dealt more with politics getting in the way of engineering and plain old common sense (like a certain Navy ship that collided with a freight ship because they had some fancy new electronic control system and a lack of proper training, of course they blamed the crew rather than the bureaucratic BS that actually caused the issue, can't remember the name of the ship or the video that covered it).

[@jackielinde7568]

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.)

[@pjm780]

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.

[@SkyhawkSteve]

that's what I thought too... based on what a buddy told me. He was a pilot of CH-46's in the Marines. Not sure how this originated... was it so there could be a single collective lever situated between the pilot and co-pilot, and the pilot had the luxury of using the right hand for the cyclic lever? I wondered how the V-22 handles things, since it alternates between rotary wing and fixed wing operation. Does the pilot sit on the left or right??

[@abominablesnowman646]

​@@SkyhawkSteve in the world of planes the pilot is on the left because you can use your right hand on the throttle.

[@knight907]

@@SkyhawkSteveYes, the early helicopters had a single collective (up/down) lever in the center. The cyclic (tilt) is difficult to control in a helicopter because it’s like balancing on top of a ball, and with most people being right-hand dominant, it’s easier to fly from the right seat. Being French has absolutely nothing to do with it. All helicopters are traditionally flown from the right seat (if there are left and right seats) due to those historical and ergonomic factors.

[@warpedfusion]

Also, France drives on the same side of the road as the US, so their driver's seats are on the left. 😂 The man obviously knows the helicopter inside and out though! I love his enthusiasm!

[@gsbeak]

Well, there is still some Frenchyness in this helicopter : "When viewed from above, most American helicopter rotors turn counter-clockwise; French helicopters turn clockwise."

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 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.

[@majorjohnson8001]

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.

[@Ben-Dixey]

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.

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.

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.

[@marcusstacey2504]

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.

[@bradpoole3943]

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

[@tonygunk1886]

Can I just mention, none of these aircraft (publicly at least) have ever gone down due to mechanical failure during a rescue! These men and women need all the credit that can be given. We love and thank you for your service 🇺🇸 Absolute legends

[@SandyMasquith]

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

[@CascadePacificNW]

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

[@kylejonesUB]

Hockenberry's enthusiasm is just phenomenal!

[@Zachafinackus]

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!

[@griffingeode]

But when is the NEXT Coast Guard video coming out?

[@RobertD_83]

"My name's Destin, let's go get smarter every once in a while " Guess that keeps you from hitting your employees with that Linus crunch... or is it LTT Krunch? Kinda sounds like a cereal 😂

[@nikkoquill]

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

[@GregMcCoy]

Dustin, I work at a simulator company. We built a hoist sim. I made a simulated explosive cable cutter. Eric Winkle Brown (top Royal Navy test pilot), he flew a helicopter on a sinking ship rescue, the sailors attached the hook to the ship railing. Eric Brown described using the crash ax to cut the cable.

[@David-wg7bj]

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.

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.

[@ronbednarczyk2497]

As an aerospace engineer who has worked in the helicopter industry for 42 years I can say with confidence that the cyclic control system does not work due to gyroscopic precession. From "Principles of Helicopter Aerodynamics" by J. Gordon Leishman "An aerodynamic forcing is applied at or close to the natural frequency of the flapping blade and the blades respond so that a unit of cyclic pitch input results in (almost) a unit of flapping response." A resonant system will respond 90 degrees from the point of input.

Nice catch, I'd have brained myself for sure

[@z06doc86]

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

[@travisolander4749]

Interviews like these are SO MUCH BETTER when the interviewer actually knows technical facts and can guide the conversation into more interesting topics. Amazing.

[@BariumCobaltNitrog3n]

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.

[@maoman4855]

Haaaaa I see what you did there.

[@caujka]

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

[@margotrosendorn6371]

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

[@GregFurtman]

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.

[@gus473]

Related to Michael F., the outdoors photographer and writer? 🤔 Duluth is an awesome place, for sure! 😎✌️

[@GregFurtman]

@@gus473 Yes, Mike is my younger brother. :)

[@joseacuna3239]

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.

[@sethmcintosh5804]

Should definitely take a look at the PR shop and see what gear the pilots and or aircrew use, for daily use and emergency use.

[@micahturpin8042]

I have been in that exact hangar! Super cool to see an in-depth look at these beautiful birds, Destin. Thank you!

[@TsunauticusIV]

Heavy D Sparks will love the Dolphin helicopter episode 🚁

[@benmol_]

Hello Destin, for the pilot / copilot seats : in France we drive on the same side of the road as in the US (but we reed our speed in km/h !). In most of helicopters the pilot is on the right side but only for ergonomics reasons (also in US helos). Planes and British cars are piloted from the other side

[@user-id4lo5re5z]

Love this series, one of the best on youtube. As a manufacturing engineer, I am very excited about this series..

[@davidecoon7964]

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!

[@Heroo01]

bit late lmfao, he even said during this video that he's already been hoisted and everything coming in the next vid. These are always edited and uploaded looong after he was there. He's even recording a lot of this video back at home explaining some stuff to us; he's nowhere near them anymore

[@davidecoon7964]

@@Heroo01 bit late or not, still gives him ideas of more stuff next time he goes back…

[@pfolv]

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

[@nicolelala10]

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!

[@tritonfit]

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

[@Farlig69]

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

[@guillaumejchauveau]

and the driver is on the left side in France, it's the british that have it on the right side I don't get it x)

[@tjsean0308]

Thank you, you are correct. fixed wing has the pilot left seat, and rotary wing has the pilot right seat.

[@knight907]

@@guillaumejchauveauYou don’t get it because what he said was nonsense. Helicopter pilots usually sit in the right due to historical helicopter design and tradition. It’s got nothing to do with France and Britain or where the driver in a car sits. 🤣

[@Farlig69]

@@knight907 Correct, it's originally due to having a common collective and dual cyclics - the vast majority of people being right handed so they need / want the cyclic in the right hand for fine control.

[@leftnut7508]

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.

[@user-mf2gr3cz6e]

Im pretty sure it's just weather observation, specially if it on a older platform such as this

[@dongquixote7138]

Based on its location, it's probably not well suited for surface search.

[@multicammando]

The guys were awesome in explaining everything and being nice and welcoming 😊
