Those with long memories will recall the F111 fiasco
At least commonsense set in and we finally rejected it when its cost overshadowed the then cancelled TSR-2 project. It was supposed to be a cheaper option, but costs escalated. You cannot help wondering if the P1154 supersonic harrier project cancelled at around the same time could be resumed for a similar budget to the F35`s as it now snowballs, we would have control of maintenance and surely it would also generate export sales.
(BTW, anorak on, the original TSR2 was the Fairey Swordfish although the T was torpedo not tactical hence logo choice)
