alt Hacker NewsYou can't really take out "the whole" air defense system because there will always be folks out with MANPAD-type things, those will score hits on occasion. That's probably what we saw here. I doubt MANPADs were nearly as common in the early 90s as they are today.
True but without radar they have a relatively difficult task of being out there setup and waiting for a fast moving jet to pass within range.
Compare that to Ukraine defending it's skies with NATO (well mostly French IIRC) AWACS feeding early data which is what made MANPADS in Ukraine so effective against Russian attacks.
