Oh.

Apparently not.

Only got to 614mph.

Oh well, another illusion shattered.

Ah, but isn't the speed of sound slower the thinner the air? Or have I got that the wrong way round?

According to

Speed of sound - Wikipedia, the free encyclopedia

Speed of sound at sea level: 761mph.

Speed of sound at 11km - 20km: 660mph

Speed of sound at 29km: 673mph.

614mph is so near but not quite there.

Why does the speed go up again from 20km to 29km?
