Getting the Minigun: Difference between revisions

Hi Everybody I'm new here (if you can't tell).

I was wondering if any of you could help me with a glitch (or what i think is a glitch) in my copy of Grand Theft Auto San Andreas. When I am in San Ferrio the bridge called the kinkard bridge the minigun is on the San Ferrio side and when i use my cheat code to get a hunter and fly above it i use a parachute and when i am falling the game stops me in mid-air like i hit land or something. is it a glitch or is the game programed that way. Any help is welcomed.
