As a kid living close to Biggin Hill we rarely seemed to miss a Battle of Britain airshow and possibly the most memorable experience to me was
watching an English Electric Lightening Display team now my memory recalls only 3 aircraft but doing a google only led me to information of 9 aircraft
called the firebirds so maybe the 3 I remember were a breakaway triple like the synchro pair of the Red Arrows.
The 3 I recall executed a very low pass and pull up vertical on full afterburn, 18 tons 33,000 pounds of thrust equals a better then one to one power
ratio so they could climb 50,000 ft per minute, ( is this still a record), anyway I was transfixed by a wall of sound that filled my whole being and
it was a lot worse for some people because as the sound subsided I could not help but notice St Johns Ambulance personnel attending to people who had
passed out from the noise, I can't see them getting away with that in the present day of health and safety.
Here is a video of a similiar event but they are not executing the same manoveurs as the display I saw and of course you cannot hope to reproduce the
sheer volume of noise in a video.
