The X-43A flew this afternoon.

4780 miles per hour.

Not bad.

Especially for a 12 foot length/4 ft wingspan!

Makes it tough to get a ride though.

Two pounds of fuel for an eleven second run, at that
rate we're talking 650+ pounds per hour. That's for a
12 foot aircraft.
I wonder what that would scale to for a fighter or
executive transport sized aircraft; I wonder about a
bomber sized aircraft...
