Recent events concerning the Aeroplane's involved were top priority for the security services. The photograph's shown on TV of part of a paxolin cct board with shielded rectangular metal boxes remind's me of a tuned cct with IF/RF shielding... Stray frequencies being blocked.?.. At the far right of the cct board is a pcb type miniature push to make Sw.
Is that a small button cell situated in the middle of the board? the right hand side of the pcb is obliterated probably for security reason's... but feel this if shown in it's entirety would reveal some sort of trigger design.
Although so far... the powers that be will reveal little to the public at large.
My own thought's are that it was a device that could be activated by R/CTL i doubt very much that the Terrorist's were negligent but deliberately left the device or device's dormant.:
NB: Whilst this was taking place and after it was not possible to get Online.
Good job they weren't and nobody else managed to dial the 'correct' wrong number!!!
You have to wonder whether the aircraft systems were somehow affected, creating some suspicion about the freight being carried...we are always told that mobile phones should be turned off for the duration of a flight.
