Spottyemm,
There is nothing unprofessional about this 767 skipper. He was not feeling unwell and his medical was in tact.The rest is between him and his doctor. He is a highly experienced Longhaul pilot who had a bad night.
The cabin crew were excel crew trained in the sop for that aircraft, all approved by the CAA so where do you get the non company crew idea from. The guys flying had been on the contract for a considerable time and probably had (and still have) a better working relationshp than 80 % of the supersilious sounding colleagues of yours. Spotty M or spotty arse you lot are just charter oiks like the rest of us and thank god it wasnt you that made a mistake waiting to happen.
