Sonic Booms
Wycombe. post 15.
Are you sure about sonic booms in the 60s?
I went to the 1954 display on the public Saturday, 5+ Sonic booms from 5 aircraft.... Hunter, DH110, Supermarine 525, Swift(535), Javelin.
As I recall it was the final week end of the three years Sound Barrier"Trials". After which "No More" at Farnborough.
Open to correction , but maybe you heard the afterburner coming in on the fast jets in the 60s during their display.
