According to Wg Cdr Andy Green, of Thrust SSC fame, "
Bloodhound represents the absolute limit of modern technology. Nobody has ever reached 1,000mph in the thick air at ground level, even in a jet fighter".
Of course, ground level extends up to 29,000' at Mt Everest but, discounting that point, I guess you could say he really means indicated air speed? On that basis, even I have handsomely exceeded his Thrust SSC record at amsl elevations 3000' lower.
Anyone claim 1000mph IAS
