|
At the July 7 Inquest in the morning session of 15th December 2010, paramedic Brian Kilminster gave evidence, questioned by Hugo Keith QC.
To set the scene, Brian Kilminster is part of the emergency response effort in carriage 1 of the Piccadilly Line train. This carriage was where the alleged suicide bomber, Jermaine Lindsay, is said to have detonated his device just after the train had entered the tunnel after leaving Kings Cross platform.
From the Inquest transcript, 15.12.2010, AM, page 37 to 38:

Q. While you were doing this, do you recollect a boom or a rumble inside the tunnel?
A. There was a rumble and a pressure wave -- like a pressure build-up.
Q. Did you subsequently discover that that was the bomb detonating in Tavistock Square?
A. I was told that after the event, yes.

Brian Kilminster is not the only witness to testify that they heard this "rumble" in the deep underground tunnel at Kings Cross.
Is it reasonable to expect the sound & pressure waves from whatever occurred on the No 30 bus at Tavistock Square - an "open air" explosion, to travel in excess of 400 meters as the crow flies, through the streets and buildings around Tavistock Square, through the entrance to Russell Square station, down the escalators into the Piccadilly Line tunnel and then travel several hundreds of metres through the tunnel up to Kings Cross so that Mr Kilminster and others could hear "a rumble and a pressure wave -- like a pressure build-up." ?
If you don't think this is a reasonable explanation then there could well be something else wrong with Mr Keith's interpretation of the cause of this rumbling pressure wave deep underground on the Piccadilly Line.
If so, what else could have caused this ?
