SASless - he's done one of those too.....WG655 into a field post total engine failure. Unfortunately the slide swerved into a tree and the crew were lucky to get out relatively unharmed.
Re the Prestwick bird (TF956) IIRC the gear was asymmetrically deployed and stuck; ie one fixed leg down, and despite a couple of hours of pushing/pulling and head scratching the decision was made to abandon her. I think the Aircrew Manual said that it was not recommended to land on one leg due to the risk of flipping over.
Lovely aircraft.....would be a tough choice between the Spad and a Sea Fury!
