A jocular flight sim that is a prime indicator of the sorry state of PC flight sims. Despite the fact that it has no real campaign system, ludicrous system requirements, a lack of detailed avionics modelling, a poorly-coded graphics engine, and more bugs than the Brazilian rainforest, it is still championed by some as the "king of military flight sims" by people who have never played Falcon 4.0
Flight Simmer 1: Hey, have you placed LOMAC?
Flight Simmer 2: No way, I refuse to poison my computer with that shit.
