And it’s hard to believe that the next bird in the pipe is even faster.

Albeit reportedly a drone....that breaks mach 6.

"Those selected for an interview generally possess a strong flight evaluation history, strong performance evaluations, and exceed the minimum flight experience requirements. Because the U-2 does not meet military specifications for handling qualities, those selected for an interview must pass a demanding three-sortie profile in the two-seat U-2 to determine their suitability for training.

Snip
 Possess at least 1200 rated hours (Notes: RMQ-1/9 Reaper time may be used to partially satisfy minimum rated hours. Do Not include pilot training or civilian time)

Snip
800 rated hours in trainer aircraft such as T-1, T-6, T-34, T-37, T-38, T-45, etc
Or
500 hours in fighters
And
Possess at least 500 hours in fixed wing, non-RPA, aircraft
And
Possess 12 months or 400 hours as pilot-in-command in primary mission aircraft

That’s the newest one I think.

My dad told me that there is always a bird in use that they don’t talk about when one has been reviled. One that is in deep testing, one in testing, one being put together and one being thought up.

My family business was making parts for airplanes before my uncle sold the company. They made parts for many planes but also for the U2, SR71 and space shuttle. I never knew what the next bird was as my security clearances wasn’t high enough to know about it.

For a jet-powered glider???

You want something with out of spec handling, that's the F-117. I'm told that without control by the flight computer, it'd fly about as ugly as it looks.

Yeah, another Skunk Works project.

The U-2 suffers greatly from the Coffin Corner problem. It's why only the best pilots are chosen to fly it. Also, in turns, often one wing tip is supersonic while the other is subsonic.

If I remember, the Coffin corner for the U-2 is + or - 6 knots. Pretty tight.

Coffin corner (aerodynamics)
Coffin corner (also known as the aerodynamic ceiling[1] or Q corner) is the region of flight where a fast fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep the airplane in stable flight.

https://en.wikipedia.org/wiki/Coffin_cor...odynamics)

And the U2 is probably the only aircraft in the world DESIGNED to operate IN the coffin corner. The speed margin for a U2, between a 1G stall and Mach buffet, is around 4 knots. That’s a margin of +/- 7 km/hr. For an aircraft that’s flying at 900 km/hr. That comes up to a margin of operational error of +/- 0.7%.

Gotta love that "you are here" display. We hosted VX-4 (think Playboy bunny on the tail) when the Navy was evaluating the F-16 for TopGun. One of their AT's let me jump up in the seat for the $1.75 tour with power on the plane. And they wonder why everyone calls them the "Chair Force".

Real talk there^^^. Currently, I'm wondering about the turn limits on the B and C models of the F-35. That beefed-up landing gear will definitely add a pound or two.

In remembering my U-2 stuff, they are also difficult to land. The aircraft want's to stay airborne and has to be forced down. The pilot has very bad ground visibility when close to the ground. On take off the wing support Pogos drop off so, the aircraft is landing on two wheels and will rest on wing skids like a glider.

To assist in landing, a second U-2 pilot in a chase car will follow the plane and call-out the ground distance to the ground blind pilot. That's how they land. Only the best pilots fly them.
