NigelOnDraft just for your info, the airport I work at has 2 runways, an inbound international flt had received a specific bomb threat, guess what the authorities did?
That's right they held it on the runway and evacuated all the pax, the a/c was kept there for the bomb squad to do their checks and then several hours later once cleared the a/c was towed to the terminal and carried on to it's next destination.
The moral is 'never say never'
