It seems an Austrian has sky-dived from the edge of outer space, some 38 km 
up, and has broken the sound barrier in his descent, landing safely via 
parachute.
   Was there a sonic boom when he exceeded speed of sound, or, due to thin 
air, no actual noise?   And, while he may have sped down quite fast in the 
rarer upper reaches, he presumably reached terminal velocity once denser 
atmosphere prevailed?
   So, what was proved which could not be anticipated?
