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

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
