An internet worker popped the question as Concorde reached top speed on its final flight to Scotland.
Rupert Pilgrim asked girlfriend Catherine Murray to marry him
The aircraft was travelling at more than 1,300mph some 60,000 feet above the North Sea when Rupert Pilgrim asked girlfriend Catherine Murray to marry him.
The 35-year-old could not get down on bended knee because he had a tray of poached salmon
and champagne on his lap.
But he still received a yes from 39-year-old Ms Murray, who said: "He chose a good moment."
The couple were among the competition winners on board the flight which left Heathrow on Friday morning.
Its 100 passengers travelled over the North Sea and then down across mainland Scotland before touching down at Edinburgh.
The supersonic aircraft set off again for Heathrow more than two hours later to complete its farewell tour.
Mr Pilgrim and Ms Murray, from Amersham, Buckinghamshire, have been together for
four years and have a 22-month-old daughter.
After the flight, Mr Pilgrim said: "I waited until Concorde was at Mach II and at its highest speed.
"When people were taking pictures, that gave me a good excuse to go up and mention to the stewards that we might want to get some champagne down."
Ms Murray said she had not known that a proposal was on the cards.
"If I'd been a man perhaps I would have thought of a similar thing," she said.
"He chose a good moment."
Mr Pilgrim added: "It was a sad and happy day for us. Concorde is an icon and we couldn't have picked a better way to travel."
