At LHR they are conducting random experiements with a body scan machine. People are randomly selected to go through this process. I have found that if I am in the right hand queue and I catch their eye, I am almost always picked.

They do the scan and then put you and your belongings right to the front of the Fast Track queue so this seems to be the quickest way through security saving few mintes each time.

The last time I was scanned I asked if I could see the images. He called to his assistant who was hidden away to freeze my images and, after the scan, lead me round. No wonder his assistant was hidden away, it was quite a shock as I looked naked! The image was slightly 'lumpy' with a blur around what was skin and clothes and you only see a white outline and no facial features obviously. The only visible items were my belt buckle and trouser buttons. Its all very strange though.
