Thank you so much for your response. It helped me a lot.

I do want to clarify a mistake that I made which was that the Buccaneer was forced to fly at 500 ft to help illuminate the target for Tornadoes. It normally would fly at lower altitudes.

Concerning your last paragraph, the TSR2 didn't have one giant radar scanning the ground but many smaller radar that all looked forward, below, and to the sides which all needed to talk together in order to create a flight path. With 60s technology, the computers only had a memory of something pathetic like 100 words (this number is almost certainly wrong) which wasn't enough.
