GTR has been playing announcements to let people travel to Luton for a flight if they have a ticket for Gatwick. I don't know how many flights have been moved to Luton, as it must be crazy out there. Hearing the airport will be closed until 6am. This is quite unprecedented, although I am sure we could have predicted something like this would happen sooner or later. I am not just concerned about who is behind this, but what potential there will be for copycat incidents here and around the world.
