Not exactly. The aircraft was picked up when their bombbay doors were opened. They were within the Radar resolution cell at that point in time and gave a fair return. Once spotted by target acquisition Radars, a target tracker can lock on with relative ease. The SA-3 Goa has a fair Radar suite that used CLOS to shoot down the Blackbird.
Not a Blackbird - more like a Stinkbug.
A Blackbird (SR-71) has never been shot down, to the best of my knowledge.
I’m sure you meant Gary Powers U2, based on the SA3 in your comment.
No SR-71 Blackbird has ever been shot down.
Go back and look from where it took off. Knowing from where/when it departs is easy enough information for locals there to cue acqs and trackers.
Yes, exactly. Multiple mobile radar sites, known flight paths, and observers were used in combination during the shoot down. My information comes from a person who would know, not Wikipedia.
