Go to the airport in Las Venturas and go to the corner of the runway. There will be a massive hanger that will go down automatically when you stand infront of it. Chec in each cornerto make sure you have the rite one. There is another hanger in the oposite corner but it is black and doesnt open. The hanger with the giant plane in must be green. When you reach it the door will open. Run in side, up the steps onto the platform and get in the 200 passenger plane. Sometimes it might not be there so try later. Get into the plane, reverse it onto the runway and get flying!! It would be good if you could do missions and take people to different places but it is solid to land because it is so big.... BUT ENJOY ANYWAY!!
