Allingham celebrated his 112th birthday with members of his family at RAF Cranwell, Lincolnshire as the guest of honour at a luncheon at the college. During the day the Battle of Britain Memorial Flight performed a flypast which was followed by an aerobatic display from two Tutor aircraft. In June 2008, at his personal request, Allingham was taken on a guided tour of the Eurofighter Typhoon aircraft at BAE Systems in Warton, Lancashire, as part of the National Veterans' Day celebrations.
