5 Pounds - Elizabeth II Last Flight of the Concorde, Silver Proof Issue

Concorde's final commercial flight took place on October 24, 2003, when three aircraft landed simultaneously at Heathrow — the last a British Airways service from New York's JFK. The retirement was forced not by age alone but by Air France and British Airways withdrawing support after the July 2000 crash near Paris killed 113 people, a disaster traced to a titanium strip shed by a Continental Airlines DC-10.

Alderney, a Crown dependency outside the UK proper, had issued Concorde commemoratives throughout the aircraft's operational life. The KM#35a is the silver proof variant of that final retirement issue, struck by the Pobjoy Mint.
