Bomb threat
At the outset let me say i have no specialist knowledge as regards bomb threats and, in the absence of that, believe that the authorities at Bristol took the right decision to evacuate the airport.
However, there are questions that i would ask which might be important to the decision as to whether or not to evacuate.
When was this note found, was it immediately after the passengers disembarked or was it much later?, or was this note seat identifiable, ie was it on a seat, under a seat, in a seat pocket or was it left somewhere else, ie a toilet.
I ask this because if the note was found immediately after the passengers disembarked, it could mean that whoever left it would still be within the airport terminal and he/she and the rest of the passengers on that plane could be evacuated into a separate area. Also, if the note was seat identifiable and found immediately, could not that person be stopped by either passport control or at another point before they left the airport?
It is the timescale of this incident that interest me, not the decision to evacuate the airport
