this mod lets you control the air craft carrier lift in San Fiero, this is scratched built by me, and took ages to find the location of the carrier lift.
instructions
1. to go down, simply press tab
2. to go back up, simply press tab again.
notes:
for missions that needs the carrier lift, like "VEERTICAL BIRD" its probably a good idea to disable or uninstal the script first, because the vertical bird mission uses the carrier lift, then after the mission, simply re-install"
