The V-2 certainly did produce a sonic boom - but audible
AFTER the impact. The warhead arrived ahead of its sound...


What you say is of course true at the impact site. I was wondering if

a
sonic boom was heard along the trajectory, long before impact. Perhaps

the
V2 would be too high for the sound to be propagated down to the ground.
Meteoroid sonic booms are generally heard below an altitude of 30 km but
more likely at lower altitudes. From what I have read the V2 reached an
altitude of around 60 miles but I'm not sure what the flight trajectory
altitude would be several minutes before the impact area. Any idea?


From eye witness reports there seems to have been no warning.
Indeed early incidents were put down to sabotage or gas explosions
