About 8 mins, the queen is talking with Prince Philip at breakfast - her pearls are under the yoke of her brown dress, briefly on top then underneath again.
The Duke of Gloucester is seen as the queen prepares to mark her silver jubilee in 1977. He died in 1974.
BOAC became British Airways on March 31,1974,the tabloid photos of Princess Margaret and Roddy Llewellyn were taken in February 1976, hence the VC-10 used for her return to the UK is in the wrong airline livery.
When Princess Margaret goes to Scotland, a train is seen crossing the Glenfinnan Viaduct on the way to Skye. But we then see her settling into her sleeping berth, obviously not far from London. And her destination is Peebles, on the Borders, a couple of hundred miles south of Glenfinnan.
