In March 2015, Les Munro, one of the last surviving members of the Dambusters Raid, intended to sell his war medals and flight logbook at auction to raise funds for the upkeep of the memorial. This was cancelled after Lord Ashcroft donated £75,000 to the Royal Air Force Benevolent Fund towards the upkeep, with a further NZ$19,500 donated by the Museum of Transport and Technology in Auckland, New Zealand, where the medals will go on display. Munro died that August.
