An X-ray machine that can see through clothes sounds like something from a sci-fi film - but it's a reality for passengers travelling through Manchester Airport.
It's been introduced to show up any hidden weapons or explosives without a full body search on passengers.
Some people are worried that the naked images are too revealing.
The airport says the black and white images will be destroyed straight away and saves passengers time.
The scanners cost £80,000 each and work by beaming electromagnetic waves on to passengers while they stand in a booth.
A virtual three-dimensional image is then created as a black and white image.
Manchester Airport will try out the scanners for a year.
