not every bit of land is at sea level.

761mph @ sea level

660mph @ 37000 ft



surely the higher you go, the less air, therefore less friction (causes drag etc)...so the faster you should go :boggle:


yes thats why Jets can travel at mach 2 high up but bearly over mach one at low level :lol:

sound is a wave remember

the air is thinner so air won't conduct sound as well so it travels slower, hence speed of sound becomes less.

yes but as the speed of sound (in mph) decreases the higher up you go the term 0.148 mach really means nothing in this case
