Heathrow early 70s

I visited Heathrow a few times in the 70s and this a compendium of those visits. This was a time of the Jumbo jets of Pan Am, TWA, Air India and BOAC. Also featured is Concorde on its return from its world tour in 1972 and the first service to Barain on 21st January 1976. Unfortunately there is no sound, The locations are the Queens Building, car parks adjacent to the runway and at the end of the runway.
