Oh I remember my training well
75 taken alive,
76 in a fix
77 kiss yer arse goodbye as your wings have folded
..I'd suspect, given the QRA response, 7500 was more like it..
Didnt Concorde used to generate a sonic boom on a daily basis west of Cornwall/Devon when in service whilst accelerating through the speed of sound over the Bristol Channel approaches?
I didnt remember hysterical headlines in the Western Daily Press as a result.
Id suggest this is all being over egged to give the impression to the world that we are on top of things pre Olympics.
If ever you are bored and want an impromptu air display or say a fly past for a wedding , spend a grand on a transponder and set it to 7500 and see what happens.Cheaper than booking the Red Arrows
Hysterical nonsense.
