the bottom line on bombing technology is that through the early '80s the bulk of bombing technology was still pretty much dependent upon the pilot putting a sight on target and counting "one potato(e) two potato(e)" as he pulled.
there were a lot of various "bombing aids" in the form of computers, radar cursors, off-set bombing, nuke countdown timers, navigation assistance, etc. One of the more sophisticated was the computer generated "fly to" cursors with an automated bomb release.
but all of that still boiled down to the pilot putting the sight on the target somehow and dropping a "stick' of bombs spread across the countryside with the faint hope that one of the many would be close enough to the intended target that the lethal radius would overlap.
As evidence of that - review radar bombing of Stanley Airfield during the Falklands War. Even more recently - the war in Georgia this past summer involved a squadron of Backfires conducting the same tactics and radar bombing technology against an airfield, with somewhat dismal results (best defensive tactic for survivabiltiy when facing an inbound Backfire raid from the Caucus Military District is to stand at the intended target point.......)
the real truth is that until the advent of guided weapons, which is pretty well simulated by the way in the sim, bombing with dumb ordanance was and still is pretty much flying the plane with a gun sight of varied sophistication on the target and letting the stick go at the right time. The sim actually does a pretty good job of representing that.
