Justapax -yes of course you are right he Viscount did sell -over 400 examples- I think which was a lot for the time. It was a lovely aircraft to fly on -I cannot compare because i never flew on a recip powered one. th 1-11 didnt do badly but its too small a gainst the stretchable (almst indefinitely) DC 9s . And yes BOAC had a lot of US aircraft but they also had the Britannia Comet and VC10s -the Comet sold quite well geographically but in small numbers and was no match for the 707-DC8 combo. The VC10 lacked range of even the early 707s and was miles behind the fan engined B and C series altho much nicer to fly on.
