I failed again, didn't I.
How about it was a different chopper? Since it had no radio contact, My mission would have been sent before the distress call. My chopper wouldn't know that there was a fight. Anyway, Shiro could be anywhere. Probably across town. He is a pathfinder so he can make his way over there.
There. much better. That way we didn't know about the fight, the crash, or the plea for rescue. AND, it explains why isn't near the fight. He is on the outskirts!
