Mach 1 is 1224 km/h
But why stop at mach 1 or 2, why not mach 3 with red glowing ships from all the air friction?
I don't think we would be able to make a single turn without having the pilot collapsing over all the G force... An 80 kg pilot doing an average WO track turn at mach one would suffer a G force of about: F=m*a (=) Fc=m*ac (=) Fc=80*(340^2)/45 (The 45m is the radius of the turn) (=) Fc=... Let me get my calculator.... Fc=205511 N which is about 256.8 G... O.O
For an admissible G force (10 G) the turn radius of the Mach one track should be of about 1156 meters... Lol That would make a turn length of about 7263 meters... Sheesh!
Talk about a huge track. I guess it could be a speed-run test track, like the ones they use to test sports cars and stuff like that. But even so those are just like 15-20 km in length! Ahahahah
