Every time I go through airport security, I’m always a bit amazed by how many people seem take by surprise over the protocol: shoes off, laptops out, liquids in bag. Is it that these people haven’t flown in the past several years? Or are they just unable to process these now-standard security procedures? Perhaps the problem is that there’s never been a hologram to teach them what to do.Thankfully, London’s Luton Airport has installed just that. Holly and Graham (get it?) were unveiled today. The life-sized holograms will be standing by the security line, alerting passengers of proper travel procedure.
