Did it melt?
Is the pilot 18 minutes younger ?
That was my reaction as well.
I’ve seen the pics of the X-15 after the high speed flight where it started to melt. Not pretty. Iirc it as determined that there needed to be a quantum jump in materials science to reach and sustain that kind of speed.
I really doubt the ChiComs are there, or if they are they’re reaching a level where we’ve already been for a while.
