An airman for the Special Forces could be sacked after he was caught taking drugs during an ‘unheard of’ crackdown in an elite unit which flies Chinook helicopters.

Compulsory testing teams reportedly circled in on the RAF Special Forces Flight, 7 Squadron three separate times in just three weeks, which led to the airman’s drug taking being discovered.

The RAF has a zero tolerance policy towards drugs, so he is likely to be booted off the force, sources were reported to have claimed.
