My school was in the circuit for Manchester Ringway (as it was back then). I can remember Viscounts going over with two props windmilling (can't remember if it was inners or outers, but I'm pretty sure it was symetrical).
A few years later a Viscount doing crew training crashed at Manchester taking off with a simulated engine failure. It rolled inverted killing the crew and (IIRC) a stewardess that was along for the ride. I can remember the wreckage, visible from the lane where the big radar head used to be (now the site of the MCR VOR). It lay under tarpaulin sheets inverted next to the runway.
I can still remember the Shadow Moss road crash of the late '50s when a Viscount (the prototype - WE?) flap bolt failed on short final. Until recently, when the row of houses there was re-roofed, you used to be be able to see the different-coloured roofs of the end two houses which were re-built after being partially demolished in the accident
