Title is correct…jet here short for turbojet ( motive power from the jet of material pushed backwards)…. turboprop gets most power from the propeller a lesser amount from jet thrust…. both turbine powered though. (Edited)

BOAC’s eyes were on the Constellation so don’t seem to have shown any interest in trying to acquire the RAF’s small fleet of Skymasters . The Argonauts had some DC-6 features like a pressure cabin but 5 years were lost

Gerald Wasley’s history of RAF Mountbatten has several pages on Lawrence’s time in the RAF in Plymouth…a curious posting for a well -connected misfit who it seems just did what he wanted to whilst there and was a pain for the career officers in charge.

The serial number gives the year when ordered…The Ray Wagner book of American Military Aircraft gives the first flight as April 1939

Since radio communications evidently were not being used to control air traffic at Ayr/Heathfield communication between Prestwick and Heathfield would have been by phone at best. They seem to have been reliant on coloured light signals yet at 2100hr BST in August it would have been still light..if very flares had been used presumably the report would have said so.No doubt lessons were learnt.
