An interesting video from a Vietnam War A-6 pilot. There's a part about SA-2s that starts at 26:45 and another at 39:40

The audio quality isn't great.

Yes, three in a row and bye-bye "Intruder"...

Just as soviets recommendations ( I also met 1 and 2 with 6 seconds interval and third after 12 seconds)...

Intruder what an amazing aircraft it was. I think it was hte first any weather aircraft.

It depends on what constitutes "any weather aircraft"

If you want the first aircraft that could navigate and bomb a target in fog, through cloud or at night, then H2S radar equiped Stirling and Halifax bombers during WW2 could be considered the first.
