There is stuff in the background you can 'find'. Reference to 'Ed Force One' on Hanger. Devil/666 picture on the Lancastern. Not sure if it is one but there is also 'UFO' on the side of a spitfire and they play in Maiden at gigs. Cardiff Simulators (Cardiff Avaition) also mentioned on a board and Bruce is CEO of that company - they lease planes out and do engineering/repairs and training of pilots I think.
