How about these'

Helicopter
First complete the mission Cop Land. Then enter the Washington Beach police station. Find the locker room (on your left) and get the cop outfit. Now enter the airbase (you won't get shot at unless you shoot one of them or start a fight). At the end of the base there will be a Hunter. If there isn't come back later. Take the helicopter. The controls for the Hunter are identical to a regular helicopter, the differences being O for unlimited missiles/unlimited and R1 for an unlimited gun.
