There are more than one hundred surviving North American B-25 Mitchells scattered over the world, mainly in the United States.
A significant number of these were brought together for Catch-22, a 1970 war film adapted from the book of the same name by Joseph Heller.
When Catch-22 began preliminary production, Paramount hired the Tallmantz Aviation organization to obtain available B-25s.
Tallmantz president, Frank G. Tallman ended up finding war-surplus aircraft, and eventually gathered not only pilots to fly the aircraft but also a ground support crew to maintain the fleet.
On 18 April 2010, 17 airworthy B-25s took off from the airfield behind the National Museum of the United States Air Force and flew over in formation to commemorate the 68th anniversary of the Doolittle Raid.
