St Athan is a military base and likely to require further large investment to provide facilities required for passenger operations.
On the other hand what people are failing to notice is that Bruce Dickinson is looking to start with three private jets. These aircraft will be based at St Athan likely and positioned to wherever they are required around the UK and Europe.
In future they will be looking at some regional jets then working towards larger aircraft. In my view this is not a case of a new Astraeus could it be likened more to a Titan Airways who has a mixture of private jets, regional jets and larger aircraft.
