At that speed, the surface of the airfoil is the temperature of molten steel 3,500 degrees Fahrenheit

Mach

F15s, even that Bald Eagle.

We didn't fly it into the Pacific.

Today, we don't talk about flying transonically, or even supersonically, we talk about flying hypersonically not Mach 2 or Mach 3, Mach 20.

That's 18,000 miles an hour, just over Mach 23!

You see, hummingbirds are not hypersonic, but they are maneuverable.

And while there's no substitute for speed, maneuverability is a very close second.

I guess I got rattled when I ejected at Mach 3.

I want hopes of prototype weapon pull a rail gun.

And in the second flight, three minutes of fully controlled, aerodynamic flight at Mach 20.

Chuck Yeager climbed into the cockpit of his Bell X 1 and he flew towards an unknown possibility, and in so doing, he became the first pilot to fly faster than the speed of sound.

In 1947, there was no wind tunnel data beyond Mach 0.85.

You can't learn to fly at Mach 20 unless you fly.

This is ugly on the ground, leaks like a sieve, but up around Mach one the seals all expand, she dries up, flies like a bat out of hell.

So that glider of yours, the Mach 20 glider, the first one, no control, it ended up in the Pacific I think somewhere.

If a Mach 20 glider takes 11 minutes and 20 seconds to get from New York to Long Beach, a hummingbird would take, well, days.

We must fly again, because amazing, never been done before things require that you fly.
