Jawohl, Herr Obersturmbahnfuehrer! Zu befehl! Orders from above - zees ve must obey vizout kvestion....
Don't be an utter ar$e. Aircrew flying clothing for those who don't wear external turning trousers ('speed jeans' in current yoofspeak) includes a survival knife in a sheath; this is restrained with a cord tell-tale. Leave it alone - and tell your spotty little idiots to understand that aircrew are unilkely ever to hijack the aeroplane in which they're travelling.
W@nker - no stick, no vote. "The role of the RAF is to fly and to fight. The role of those who don't is to SUPPORT those who do"- not to irritate them with utterly banal and totally irrelevant rules. Never lose sight of that!
