As for whats going on the rumours are 4 guys arrested, all alive, 2 at the RAH. Airport closed until 2100. Major incident trucks set up in the taxi rank outside the Loganair hangar. Several ambulances and tent errected there as well. All access to airport closed. We've been told we can't leave in our cars.
