Attempted Robbery In Cape Town
ChatterBank1 min ago
the americans broke the sound barrier at around 660mph in the air.
Britain broke the sound barrier at 763mph on the ground with Thrust SSC.
why is there NO set speed for sound ? even on the day Thrust set the record, his speed could have been faster or slower and still have broken the sound barrier. i know its partly to do with atmospheric pressure and moisture in the air, but i cant work the maths !
