Cold War Aircraft Design
Spending the festive season re-reading some of Bill Gunston;'s books and was struck by the number of times one side would develop a type and then the other would immediately start building something similar.......
Why?
Was it :-
1. OMG we have to have the same as them just in case
2. OMG they've spotted a scenario/role that we missed
3. NOW those b******* in Red Square/Congress will listen to us
4. Wow! another opportunity to fill our factories in Long Beach/Kazan with something new and profitable..............
