British and American aircraft joined forces this morning for an historic flypast to commemorate the 75th anniversary of a plane crash tragedy.
On February 22, 1944 the American aircraft Mi Amigo crashed into Sheffield's Endcliffe Park. All ten crew members on board were killed.
Pensioner Tony Foulds, who was one of a group of school children who were in the park on the day and witnessed the tragedy, has dedicated his life to caring for the memorial to the airmen in the park.

And people in Derbyshire were able to catch a glimpse of the aircraft as they made their way to the flypast.
These video clips have been sent in by Rachel Stack, Jessica McBain and Amanda Raben.
