Coningsby, an F4 squadron getting tacevaled, generation phase. The boss was away on leave. The Flt Lt on ops turned to the taceval man and said that he had the boss's contact number and could recall him if required. What did Mr Taceval want?
'Do what you would do for real.' was the instruction.
'I can't get a nine mil round down the phone line!' was the memorable reply.
The whole ops room fell about laughing.
