Quite simply because of incompetence by some RAF Officers. They couldnt get their act together and actually save the MOD and most importantly RAF Weston on the Green / JSAT money. Skydive Weston offered up to £500,000 of income over the next 5 years but they said no.
They blindly gave the gliders a new 10 year lease, who dont contribute anything to JSAT or have offered any kind of income Thats no fault of the gliders who are a great bunch.
An obvious reason why the Defence Budget is in the state it is when you have incompetent Officers pretending they know how to control budgets!
As the RAF are the teachers of military parachuting, its quite bizarre they have no facility for their guys to do sport parachuting at weekends now, when the Army have 4.
Even the RAF Falcons had to go to a civilian centre to jump their own Charity tandems for the Parachute Jumping Instructors Benevolent Fund, as they were not permitted to do them at RAF Weston on the Green, No1 PTS own training drop zone!
As an RAF Officer said the other day "The RAF is coming to the end of its hundred year experiment"
