Best interview I’ve seen, could listen to Rogers all day! I’m sure there is a lot more he has to share. Please have him on again for parts 2,3,4,5,etc….Great show!
@@FighterPilotPodcast that’s great to hear! You always do an outstanding job with your podcast. You and Ward Carroll have the 2 best podcasts I’ve found. Always well presented.
Argentine Air Force Pilot here. I'm impressed by Rogers' humble anwers. There are several sharp and meaningful quotes to highlight; I will add most of them to my future test pilot presentation but, I will keep this one for me *"I wanted to be a test pilot because I love my uncle"* This statement has really impressed me.
British Royal Navy test pilot, Captain Eric Melrose "Winkle" Brown, flew 487 different types of aircraft, including Russian, British, American, Italian and 53 German types, one of which was the Me163 rocket fighter, and the three German jet types which were used in WW2. That record includes only the basic types, omitting variants. Therefore the total number of distinct models he flew was well over 500. His record is unlikely ever to be broken. He also held the record for being the first person to land a twin engined aircraft on an aircraft carrier, the Sea Mosquito. To do that, he had to stall it onto the deck. Another record he held is the greatest number of carrier landings; over 2,400. Brown was a personal friend of Ernst Udet and Hannah Reitsch, before and after WW2. It was Udet who encouraged him to learn German and to learn how to fly, in 1936. The BBC featured him on radio and TV a number of times. Some of his BBC interviews and several of his speeches are available on RUclips.
Wow what an interview! And this man has certainly learned what it takes to be a test pilot for one but also a leader. A fascinating career and the number of different types he's flown is mind blowing.
I watched this interview with Rogers 2 times and loved every bit of it. I shared the video with my churches pilots (including a former Navy pilot, who retired and she is now an American Airlines 777 Captain - she loved the video.) and prayer group. Amazing, wonderful interview. - I also shared Brian Schul's (the "Sled Driver") videos. I noted that Rogers spent 1 month studying the SR-71 A-1 Flight Manual and using the simulator. Brian Schul said is took him 4 months.
“Maybe sometimes you can have too much.” Brilliant observation. My wife trained as an RN. Setting up an I.V. drip can be done manually and it is taught in school but never practiced in the field. Very soon you become dependent on the machines and forget the fundamentals.
As an aerospace engineer myself and glider pilot, I've always dreamed of also becoming a test pilot, exactly like this wonderful man called Rogers Smith, just because of the greater freedom of testing things in a plane can offer, yet I've been born in the wrong country at the wrong time. I hope I can do this in the afterlife! Great video. Thank you very much for it.
Great discussion on the Soviet/Russian design. I wish you could bring him back to talk more about the design philosophy of Russian aerospace engineering.
@@FighterPilotPodcast 2 amazing hours! And to be fair, I could listen to any of your interviews for hours and hours! ;-) Thanks for such great content. Love the new video format too!
That comment about HR rings a bell. I worked in engineering for years, after having done research at a few places, one of which was CalTech. My first day was amazing: my mentor told me to get my keys from "HR", two people who's entire job was to make sure we had everything we needed with a minimum of "interference". Only experienced this once in my succeeding career.
Excellent episode. I got to know Rogers at SETP/SFTE in Dallas in 2013. I also heard him speak at the recent SFTE symposium that he mentioned in the interview. Really nice guy and a legend in the field.
This guy is and has been living the dream his entire life and he is still contributing to the development of aircraft and testing of aircraft and he still has so much to offer
Rogers, I promise absolutely no one thinks you're bragging or living in the past & I think I speak for all of us here when I say we're happy to hear about your career & what it may teach others.
I knew a guy just like him. Was a pilot but really an Engineer. Always was how can we get this to work better? Thank you so much. Was a walk down memory lane. Appreciate.
I was the flight line sweeper operator at Edwards from about September’89 to May ‘90. Got to see a lot of the aircraft that Mr. Smith got to fly back then! Excellent interview! Thanks!!
These guys were, are and will forever be my true heroes. Absolute cowboys with bottomless courage facing the unknown. Aviators of the Cold War, from the golden age of jet aviation when technology was rapidly changing, but where man and machine were still one. To have lived such a life...the stuff of my dreams.
Subscribed almost instantly after watching the clip of him talking about the SR-71. I love hearing stories from fighter pilots. Looking forward to watching more of your podcasts.
Absolutely awesome, all the episodes are really good, a pleasure to listen to. Thank you very much for all your hard work in bringing amazing stories to the listeners 🙏👌
I had the privilege to fly out of Edwards in the early 90s. It was a great environment to be in and the highlight of my flying carrer. NASA still had the F8 and F104 at the time and on any given day you could see F104s flying chase on the SR-71. Some of the test programs going at that time included the B2, YF-23/22, X-31, X-29, C17, and T-45. Chuck Yeager was hired as a consultant by Northrop-Grumman (where I worked) on the F-20 program. Company press releases reported that he had evaluated the airplane and he endorsed it in a Northrop commercial. I saw him several times on the flight line wearing a flight suit but can not confirm weather he flew the airplane or not.
I was working in ops engineering at Dryden 1990-92. He took for a memorable ride in the T-38 just before I left to go to Air Force pilot training. Fun was had!
The early guidance for the bombers was called GEE and used two overlapping radio signals to make sort of grid squares they could use for reference by judging distance from the signals.
Legends. I wish this country would champion its values like it used to. Pioneers, people to look up to. Men and women that change the fabric of society we inherit from them. These people mean so much !
But, we have the Kardashians… what more could we need? Jk. Totally agree. I do think people still value all that stuff today. Over 400k + people watched this video
I learnt the importance of checklists in aviation and the need for meticulous attention to detail, even in the face of unexpected situations. Thank you for sharing
🌹🌹🌹🌹 he reminds me of our Ww2 dad.. looks so much like him.. and his personality/ face expressions…, his lack of self centred-ness/ ego…. An absolute hero to us🙏🙏🌹🌹
Truly excellent interview. I still wonder if he was the SR-71 pilot we got a talk from at my University at Munich, aerospace department probably around 2005+- . At least the EADS Munich ties speak for it. We had X31 and Hypersonic research going on iirc. I just remember the SR flight manual was still locked away back then in my departments library 😊 Cheers, Georg M ;)
I can remember being at Grumman on long island with my dad when Chuck Sewell was taking the x 29 down the runway over and over (just short of takeoff) He said the airplane was dying to get in the air, but Riverhead was not the place for that. Met him a few months later at the mall, his grip could crush your hand without even trying. Was sad to heard he passed in a crash..
I grew up in Acton then Palmdale (i’m old enough to remember when the skunk works hanger was where they made L10-11 Tri-Stars) we saw SR 71s so often we would just take it for granted you’d be out at PE or something in there it would be. I only saw the space shuttle piggyback once I’m not sure if it was an Enterprise training flight or if it was Columbia returning to the Cape. I know it’s not cool to say you live in Palmdale, but just for the aviation alone, I wouldn’t trade my childhood years for anything. Great Podcast!!
great interview and what a guest - so detailed and sharp still at his age (he didn't bring it up so I won't either but he don't look his age at all). proud to be a fellow canuck.
Those variable-stability can do that, and they can also vary control force gradients. Outstanding tools for both training flight testers and testing new flight control laws in the air.
On the night before the the 50th anniversary, Yeager gave a talk to family and friends at the Essex hotel in Lancaster. The sound system played in the lobby so I got to listen in. I saw him flying the next day (from Mojave) in a three ship formation (the third plane was for pictures, I guess).
I wish I would have all the stories of my Uncle Hans building his plane. Wait, I have the pictures! I will tell the story from at the time of a 10 year old. Thank you for sharing these stories
Great guest and great interview! It may have been interesting to also have one of your test pilot / engineer hosts too. Just a suggestion I'm not complianing.
Great first hand history. The questions I wanted to ask. 1. What was the worst aircraft he flew. 2. Was there any aircraft he looked at and did not feel positive about flying it.
Simply awesome, I love details & this video with Mr. Smith or Rog is 😍 a living legend & I like a lot of the other comments here, agree. I onder does height make a difference for fighter pilot's? This is the first time I have listened to these stories 🎶. Talent plus skill & a little luck, equals special pilot's, like Mr Smith (Rog). Has my full respect. Never too old to learn & I did today.

The SR-71 inlet spikes are carefully designed to capture the supersonic shockwave generated by their points. The spikes translate fore and aft to bring the shockwave which is shaped like a cone, up to the outer lip of the engine intake. This shockwave is captured and bounces around a certain number of times, ending in a normal shock (perpendicular to engine face) and the air is then subsonic for the engine compressor blades to function properly, the air is also extremely dense and hot, its about the same pressure as at sea level when at mach 3.2 at ~ 85,000'. (Where air pressure is only around 3% of sea level pressure). So, the inlets capture the extremely high static head from high speed and bring it down to subsonic velocities before the engine compressor blades ingest it. An "Unstart" is due to the inlet spikes not being in the prefect position allowing the shockwave to enter the inlet at the wrong angle, messing up the pressure-recovery, and "un-starting" the inlet, which reduces thrust in the blink of an eye and makes the pilot think he was probably shot down. The inlet spikes were very accurately controlled, but the tempura causes them to grow over time due to expanding metal/materials. And also, flying thru pockets of air that is colder or hotter. (lower speed of sound in cold air changes the mach-angle and causes the shockwave to widen and miss the inlet lip). This is per certain SR-71 pilots and engineers or specialists who theorized about what was causing it. And un starts were never fixed.
@@FighterPilotPodcast ah, thank you. i wasn't sure what he said. After a quick google of "unstart", it's like a backfire from the J58 that causes a quick violent yawing of the aircraft, like someone jerked the steering wheel to one side of a car.
Great interview! Do you know or can you find if the super sonic anniversary flight in '84 or '85 with the dark green F-111 (on the deck, 10-12' off the ground) had Chuck Yeager in it? I was there, about 50 yards away. I was either 9 or 10 depending on which year it was. I was unaware that the man himself did ride alongs on those and was curious if he was on that one. Thanks
Roj is a friend and I consider him to be one of my mentors. We worked together on many projects. I have unfortunately lost touch with him and would love to reconnect.
Really interesting abut B. Schul. I got the sense that whilst people have flown the SR in anger, guys like Rogers were the silent brains and grit behind stuff like that and who knew what they were dealing with. The SR71 is definitely not a chevy, it's an ungodly piece of man made American engineering marvel which has and will likely never be made or seen again in our life time unless it is a scramjet with new materials and unmanned.
Thank you for putting these people on film as long they are still available.

Rogers with an 's'! 😉
What an amazing life. Very fortunate and humble guy. Guessing he's the only one to have ever flown both the SR-71 and the MIG-25?
51:45 I had a picture of it on my wall as a kid too!
Great flying stories! Rogers needs to write a book or two.
Believe he is considering just that

I have, and it wasn't a contest.
14:00 They build a stable aircraft to behave like an unstable one? That is awesome! They need one that has a dead time for training against PIO.
Those variable-stability can do that, and they can also vary control force gradients. Outstanding tools for both training flight testers and testing new flight control laws in the air.

28:21 " if you think safty is expensive, try an accident. That 's the trade off."
What is an "on start"?
An “unstart” is an engine malfunction unique to the SR-71.
The SR-71 inlet spikes are carefully designed to capture the supersonic shockwave generated by their points. The spikes translate fore and aft to bring the shockwave which is shaped like a cone, up to the outer lip of the engine intake. This shockwave is captured and bounces around a certain number of times, ending in a normal shock (perpendicular to engine face) and the air is then subsonic for the engine compressor blades to function properly, the air is also extremely dense and hot, its about the same pressure as at sea level when at mach 3.2 at ~ 85,000'. (Where air pressure is only around 3% of sea level pressure).
So, the inlets capture the extremely high static head from high speed and bring it down to subsonic velocities before the engine compressor blades ingest it.
An "Unstart" is due to the inlet spikes not being in the prefect position allowing the shockwave to enter the inlet at the wrong angle, messing up the pressure-recovery, and "un-starting" the inlet, which reduces thrust in the blink of an eye and makes the pilot think he was probably shot down.
The inlet spikes were very accurately controlled, but the tempura causes them to grow over time due to expanding metal/materials. And also, flying thru pockets of air that is colder or hotter.
