L1011
Cathay made huge profits out of the L1011 because they got about 10 aircraft from the Arizona desert for "peanuts", refurbished them and flew them on high density routes. As for the input of the Brits into the autoflight system, that was a very strong "urban myth" within HK which indicated that the British Trident team was heavily involved. If you know something which differs from that "urban myth" 411A, please share the info with the rest of us. By your own admission, (Tech log Cat IIIC thread 2ndMarch2009) Smiths and Hawker Siddley who designed the Trident autoflight system are the ones to thank for the L1011 precise Autoland system.
