I'd be delighted to be proved wrong (the T4 is the prettiest FJ in the inventory today), but I was under the impression that a "Mk 8 Canberra" was about as sophisticated as the CAA were prepared to tolerate - hence the problems with Lightning and Buccaneer.
I was led to believe that it's all of the reheat, high pressure hydraulics, AVPIN starters and all the other malarkey of post 1960 fast jets that terrify the CAA rather than the handling aspects - so I guess the question is how 'complicated' is the Jag T4 in a 'systems' sense?
And if you want a PPL-holding press officer with a proven interest in the Jag, and more than a few Jag T2/2A backseat rides under his belt, then look no further.
