I heard that British airport security had a policy of disposing of electronic equipment if you were unable to prove that you can turn them on. Is this true? What if I am carrying a spare insulin pump or a similar medical related device which could not be turned on at will?
OK So I went to the airport. I was carrying the official documentation for my device signed by the manufactures and doctors. I was allowed to not put my device in the xray (in case of damage). The device was swabbed and they did not require my to turn it on. The documentation given by the manufactures explained why this was so and contact details etc. The security staff said it was fine and I proceeded with my travel. This was exiting the UK.
