"Grumpy" is a 1943 RCAF B-25D Mitchell. This plane was supplied to the Royal Canadian Air Force as KL161 during the war. Nowadays, plane is owned, operated, and flown by the Historic Flight Foundation at Paine Field in Everett, WA (KPAE). It is the oldest B-25 in operation on the globe. It wears Royal Air Force camouflage and the markings of 98 Squadron (codes “VO”), one of the few RAF units to fly B-25s operationally.

B-25 Mitchells fought in every theatre of the Second World War and operated in many roles, including tactical bombing, tank busting and anti shipping strikes.They were used by many Allied air forces.

In the public mind they are remembered almost exclusively for one propaganda raid, led by Lt. Col. James Doolittle, which struck targets in Japan from the aircraft carrier USS Hornet on April 18, 1942. But an interesting is that only the British flew B-25s on operational bombing missions from the United Kingdom into occupied Europe.  

This footage was taken in Everett Washington during an event in June 2014.
