Service personnel from RAF Halton have exercised their freedom of Aylesbury with a parade through the town.
The event has been taking place every four years since 1956 but with RAF Halton set to close in 2022 this could be the final time the parade is seen in the town.
RAF Halton Station Commander, Group Captain James Brayshaw, said it was a privilege to parade through Aylesbury and was optimistic that it would not be their last opportunity.
"I truly hope that before Halton closes, that we exercise the freedom of all the towns in the area"
The event was marked with a flypast by a Dakota of the Battle of Britain Memorial Flight.
The Douglas C-47 Dakota was one of the world's most famous military transport aircraft and saw widespread use by the Allies during World War Two.
RAF Halton is one of the largest RAF stations in the UK.
Its primary role is to train personnel for military operations.
