I started out reading this article in which the British team Bloodhound Supersonic Car is being prepared to go 1000 MPH on land.
Out of curiosity, I looked up the fastest air speed record. I came upon this article in Wikipedia Flight airspeed record - Wikipedia, the free encyclopedia As I was interested in what the fastest speed was, in no particular altitude or class of aircraft, I looked at the bottom. What I found is either grossly incorrect, or nigh incomprehensible:
November 16, 2004 Unmanned 7,546 MPH 12,144 KHM NASA X-43A Air-launched hypersonic scramjet
If my math is right, it would take 23 minutes to traverse the United States!:popout2: Really incredible. Again if my math is right, it would take approx .697 seconds to go 1 mile. That is truly amazing!
