I seem to recall it spent a lot of its time in a state of combustion. Spud Murphy had it climbing out of London one night and couldn't understand the gabbling R/T. Eventually a bilingual BUA chap said: "London, I think he's trying to tell you he's on fire". And if I had a quid for every time the bloke at Fairoaks rang to complain about a "large 4-engined aeroplane flying through my circuit trailing smoke". Happy days Jack!
