What seems so be missing from this dicussion is no one said "manned
supersonic
flight."

The first unmanned supersonic flights were some types of bullets fired in
the
late 1800s. As far as flying machines being super sonic the Nazi A-4 did
it
before the Me262 even flew.


I assumed by "flight" the discussion was limited to airborne vehicles.

Of course

Just injecting a little levity. I do this with people who tell me "before
Yeager no one believed supersonic flight was possible" or that "it was thought
the sound barrier was impenetrable." In this case there seems to be some
arguing so I decided to lighten things up a tad.
