The problem is that eventually it reaches complete paranoia where you become completely unable to assess a threat and end up reacting when you shouldn't, doing nothing when you should, over-reacting, under-reacting and so on.
People that I was around seem to think the Soviets were supermen when it come to getting to our innermost secrets.
If anybody's got any answers on the above, I'd love to hear it but, otherwise, to get back onto topic.
I'd say the A3J/A-5 was an interesting flop in the role it was designed for because of the following
It might very well have been able to meet all of it's speed requirements
It was able to get on and off a carrier deck (however hard that was)
It had advanced features
That being said the major problems it had seemed to be the bomb-train: While the design was otherwise quite impressive, the bomb-train seemed to be a train-wreck. From what I remember
It didn't necessarily clear the aircraft which would be a major problem
It allegedly came out once on the ground, and assuming that wasn't the only time, I could imagine that even if it didn't kill anybody, it'd make your heart skip a beat!
The after body was grossly altered after the bomb-train was released and I'm not sure how that would effect drag
My guess is that the bomb-train was to eliminate the need for a post-target turn and possibly to improve ballistics.
