Check out this high-flying cleaning job!

You've probably seen people suspended from tall buildings before when they're cleaning windows.

But what about cleaning planes?

These aircraft are part of the Royal Air Force Museum in Shropshire, and are being given their annual big clean.

It's a particularly important year for the museum as the RAF mark its 100th birthday in April.

So these specialist cleaners are making sure everything is spick and span by then.
