UK foils airline terror plot against four cities

A terror plot to attack four cities across Britain was foiled by the authorities after they intercepted two foreign airline pilots, believed to be sympathisers of ISIS, discussing the targets, a week after the Paris terror attacks.

The two commercial airline pilots, one of whom was flying for an airline on an intelligence service watchlist, were intercepted talking about the plot and the information passed on to Britain's spies at the Government Communications Headquarters (GCHQ).  The conversation was intercepted by Royal Air Force (RAF) operators on the southern coast of England.
