Hello,
ReplyDeleteSorry to disappoint you, but 800 km/h is not Mach 0.8. Soud speed at sea level is approx 340 m/S, i.e. 1224 km/h. So 800 km/h is Mach 0.65.
Still, very impressive spedd achieved !!!
Regards.
Corrected :)
ReplyDeletespencer is the man, when i tell my old duffer friends here in montana about the speeds, some of them wont belive me even with the video
ReplyDeleteIs there any video ?
ReplyDeleteRemember 498mph was groundspeed not airspeed. Max airspeed is estimated at 580mph. Also temperature was 20deg F. Put this into mach speed calc and you get m=0.79!
ReplyDeleteYes - search 498mph on Vimeo
