[SOC] Concorde

[Chris Redding]

Well, sonic booms generated in the thin air at 55000 feet hardly make
more than a small dull double 'thump' by the time they reach the ground.
Most of the pressure pulse dissipates as it tries (and largely fails) to
affect the progressively-denser air below.

I've heard many sonic booms when at sea with the 'Grey Funnel Line', and
they are not all they are dressed-up to be. More like distant
cannon-fire - more felt than heard.

I would strike a compromise, and only allow SSTs to transit land during
daylight, as the sound is far more noticeable in the still of night.

All of the in-service Concordes were 'dual registered'. they also
carried 'N.........' numbers. to allow operation in USA airspace around
JFK.  You see, American-registered noisy planes were welcome in US
airspace, but British-registered noisy planes were not.

Nevertheless - your F14, F16s, and B52s, will always be welcomed in UK
skies (except by the usual few).
