There's something not quite kosher about this whole thing. Too late now I suppose to test their blood for anything additional to alcohol? I spent time in the RAF when getting legless wouldn't raise an eyebrow but I never ever saw anyone reach the stage of 'lying in a gutter'. Let me think, Bugis Street, Cyprus, Malta, Oakham, Bahrain, Gan etc etc. Nope; never.
Typhoon pilots the night before shooting ops? Very strange.
