This was a use of Runway 05 that I remember from my early days in ATC.

I think that the engine fell near Staines, not Hounslow as stated in the above article. It was a superb bit of flying - departing from 28L and a tear drop to land on 05, all in about 5 minutes.
I had recently moved from Heathrow to LATCC as an ATCA, prior to commencing my ATCO training.
Later, on completion of my training, I was posted to Farnborough where I saw the engine in the AIB hangar. It was only about 4 feet long.
