In Hindsight: You can only choose one. Which would you choose

two choices. competing designs, was the right aircraft chosen? or one design that was cancelled but led to the development of another.. was the right one adopted? in hindsight what do you think should’ve been chosen

1. Mirage 4000 or Rafale: Choose the 4K earlier, which probably wouldn’t have led to the development of the Raf, or go with the Raf like what happened
2. Mirage G or Mirage F1: 1 year apart, one chosen. would you have gone heavy or was it correct to stay light?
3. EAP or Typhoon: Should Britain have gone alone?
4. EAP/Typhoon or Rafale: Should UK and others have allowed France to have their way for the design?
5. YF-23 or YF-22: was the YF-22 the right winner for ATF?
6. X-32 or X-35
7. Yak-141 or Su-33: which was the best choice for the Kuznetsov and early Gorky
8. MiG-AT or Yak-130
