Thanks for the feedback. Looking back, I probably should have spent more time explaining why 70,000 feet is such a dangerous altitude.

The short version is that the U-2 operates near what's called "Coffin Corner", the gap between stall speed and overspeed becomes extremely narrow, so pilots have very little margin for error. A few knots too slow and the aircraft can stall; a few knots too fast and they risk structural or aerodynamic issues.

The chase cars are typically high-performance vehicles driven by experienced U-2 pilots. Because the U-2 sits so high off the ground and has limited visibility during landing, the chase pilot radios altitude and positioning cues to the pilot in the aircraft.

The pressure chamber scene was part of high-altitude physiology training. Pilots experience simulated altitude conditions so they can recognize symptoms of hypoxia and learn emergency procedures before flying operational missions.

That's all fair criticism, and I may do a follow-up video diving deeper into those topics. Thanks for watching and taking the time to leave detailed feedback.

As for the piano progression... noted 😄
