Planes from the RAF Museum Cosford have had their annual clean - at great height.
Cleaning the planes takes a very experienced crew, who use harnesses and ropes to give the flying machines a sparkle.
There are 20 planes in the museum so it's a pretty big task.
Check out the video to see the cleaners wing walk and get rid of all the dust.
