The only reference I know of between Global express and the word ASTOR is the long awaited and over budgeted ASTOR project To you the Canberra PR9 replacement long in the planning, late in the Delivery, and as stated well over Budget.
The only MOD procurement that comes close to beating the Tornado,s record for delays and over pricing.
One delay I understand was the insistance on carrying the Hughes camera ex U2 1960 tech, " What do you mean it won't fit through the door cut a whole in the side like we did with the Canberra, What do you mean you can't because its pressurised whats pressurised anyway !!!!!!!
If the plane was there look for a big truck its part of the package gives the generals actual time data of the battle field. bit like the US Global Hawk but 100 times more expensive.
