Return Flight – Dead Of Night BBC

Not sure if it belongs here, but just watched this old TV programme with an intriguing plot about history repeating itself, and a pilot haunted by the past:

Whilst it shows its age, it isn’t a bad piece of supernatural drama, and it features a Lancaster briefly, along with what I think might be a Bristol Britannia (playing a jet!)?

Does anyone have any clue which aircraft it (The Britannia?) is incidentally?
