Ah, it's Have_a_go_at_F3's Day. (mods, we need a gallic shrug shoulders icon)
1. If you operate in uncontrolled airspace, know what you are doing. This guy didn't.
2. We didn't build the radar, just tried to get the best out of it.
3. Incomplete radar pictures were common for almost all air defence aircraft at that time, which is why all AD crews were trained immediately for 4-ship leads as anyone might have the best air picture.
4. Never heard of individual IFF codes, but that was nav **** anyway
