Deltajets are also looking at Jaguar T4 purchase. Buying it is the easy bit - getting it flying might take the odd miracle, but we are working on it.
Perhaps you would be good enough to contact them - 01285 771494 and get hold of the Chief Pilot.
I am sure we can help each other somehow.
He's a good looking chap and incidentally has 3500 hours on Jags!
