Ah TURIN, the Pegasus is very reliable as Mr Farley will testify but the 146 isn't HA!.
Years ago at the Farnborough airshow I saw a model of a VSTOL airliner that Hawker Siddley were looking at. It looked like a 757 with two lage fairings extending out from each side of the fuselage, running nose to tail. These housed lift fans driven from the two wing mounted engines. With the lift fans concentrated very close to the centre line of the aircraft, if you lost a lift fan you wouldn't have such a disasterous out of ballence effect as with a VSTOL 146.
The moldel is saw was in B.E.A. livery and it was on the Hawker Siddley stand. So that puts it early 70's!!!!,
Oh yes some bloke in a sandy coloured Harrier was making a dreadful racket!!
