Introduced into service in weeks rather than years by bypassing the BD setup in total.
A simple statement that proves your lack of knowledge on the subject:
From 'flash to bang' (as an ex-boss would say,) the process from being given the go-ahead to first ac delivery was one year and one week, IIRC. (That's 53 weeks to you, if you wish to be pedantic.)
Bypassing the whole BD setup in total? No.
A document audit/trail was done well before the first ac arrived in UK, (to forewarn/foresee of any potential showstoppers,) and at least one frame visited BD for a short period of time for RF compatability testing IIRC.
Btw, it's "tp" and not "TP".....
