This
story from Reuters is a classic.
Detectives halted the London-bound flight at Durham Tees Valley Airport and Harraj Mann, 24, was taken off.
The reason for taking him off for questioning:
The taxi driver had become worried on the way to the airport because Mann had been singing along to The Clash's 1979 anthem "London Calling," which features the lyrics "Now war is declared -- and battle come down" while other lines warn of a "meltdown expected".
Maybe that
band from Florida is right - the UK is a dangerous hotbed of terrorists singing along in the taxi...
