Please also download the supporting add-ons:
Interactive Vehicle Support - https://blocklandglass.com/addons/addon.php?id=163 - Without this you won't be able to raise the gear or open the doors
Vehicle Dismount Support - http://www.mediafire.com/?282j3dpv97l2yq6 - This puts your player just outside the front left door instead of in the middle of the plane when dismounting
