XO...
here here, good to see someone in the know nipping this kind of crap in the bud for once. Well done!
Having done my time with the funbus fellows I know that all sorts of snags can leave you stranded down-route, and the reason it "always seems to happen" downroute as opposed back at home is the obvious lack of spares (parts/ac) in random places. (Admittedly it is sometimes due to hilarity.... a week spent in canada due to having a lovely empty nosecone packing crate sent to us... really useful!)
Wish people would stop digging at the multis chaps and realise that their kit is even more antiquated than that which the rest of the aging air force has to cope with!
