Some Argonauts ended up at Derby Airways (later British Midland) and operated off grass at Burnaston (now the Toyota car plant). One (G-ALHM???) in BM colours came to grief on the approach to Manchester in the late 1960s, crashing in the centre of Stockport with much loss of life to those on board.
I remember cycling there the next day to see it - the incongruous sight of the big tail section with 'BM' on it in among the buildings of the town.
