Oh, sweet jesus, I had that happen once in my entire career of bombing, and I still remember the sting!
I don't think you can do away with it though.
Without it, whats to stop a "Friendly" bomber from hovering over his own base and carpet bombing a mission rolling down the runway.
Take it with a grain of salt. Chalk it up to terrible luck.
Too bad, Sandman. I know how bad Killbomber sucks, but 2 years later, I do laugh about my incident.
