I went through on Monday late afternoon and I was the only person in the whole of security. Staff are still learning the machines and the young lady looked quite perplexed when she saw the image of my bag, it didnt go for secondary but asked anyway if they would like to have a look so they could marry up an image to a real view.
I do like the new body scanners, not sure if they will be quicker or slower once passenger numbers start to grow again as we get into the holiday season.
