The people in the Blue Jays’ organization who contributed to Yesavage’s supersonic rise tell stories about their brief interactions with him as if they are recounting the origin of a veteran ace in his twilight.

The fast solar wind -- a supersonic stream of charged particles -- originates mainly in the Sun's polar coronal holes and fills most of the heliosphere, shaping conditions in interplanetary space.

In terms of purely destructive power, however, hypersonic missiles are not hugely different from supersonic or subsonic cruise missiles, according to Mr Freer.

These too will be flown by RAF pilots, at supersonic speed.
