CL-44 Transmeridian Air Cargo.
I don't recognise the airport (but the snow looks familiar).
Used to knock around Stansted, though at one time some were on lease to British Air Ferries at Southend.
The Tradewinds Aw were regular at Gatwick.
on looking at the surroundings.. it looks like my local.. Teesside or Durham Tees Valley now... never seen this one but Tradwinds ones were a more common sight in the early 80s..
