More interaction with the helicopter in the Helicopter Event would be nice. At a bare minimum, being able to tell WHAT KIND would be nice-the average schmuck could say "colorful helicopter, drab helicopter, helicopter with guns, big helicopter, little helicopter"; a Park Ranger could say "military helicopter, news helicopter, transport chopper, private helicopter", a Veteran could say "Boeing AH-64 Apache, Bell OH-58 Kiowa, Bell 206A JetRanger, Baby Belle" so forth and so on. Being a Veteran, Park Ranger, or similar profession might let you tune in with a Walkie-Talkie and address the pilots-for good or ill-and at the very least, get them to move away before they attract the zed.
In certain cases, maybe even get them to scout the area for you?
I don't really expect them to be able to fly you to safety-that's not really in the name of the game-but hell, just being able to learn where other settlements of survivors are and maybe establish trade would be nice.
