There is obviously some additional modifier missing here, since even 
if the X-15 is disqualified since it used a rocket engine rather than 
an air-breathing engine, the SR-71 is still considered a jet aircraft 
(even if it uses exotic fuel) and is piloted 
(<http://en.wikipedia.org/wiki/Eldon_W._Joersz>).


Sorry, I was doing meters/second and didn't give units like I meant to. 
1000 comes out to 2236 mph, a bit more than your source which claims 2188. 
Maybe the 2236 wasn't quite official for some reason.  But, we basicaly
agree here. And yes, I didn't consider rocket planes, and didn't consider
the shuttle, etc.
