Ironic isn't it. I just caught up with reading some threads, this one included, before setting out to go LHR HKG on CX250 last night (as slf)
Snoozing away NE of Moscow some 3 hours into the flight when the captain apologises for the flames that some people have seen, no2 is shut down, and we're turing back to LHR. 4hours later, coming back lower and slower, and we land at 2am!
Must say though, just in case any journos are reading, that the whole thing seemed extremely professionally handled, with absolutely no panic amongst the pax. Just some moans about being late for meetings!
