Trevor's planning to hijack a military plane while in flight and steal the cargo. What could possibly go wrong this time?
Drive to Michael's house as Franklin and watch the cut scene.
After the cut scene you will be automatically switched to Trevor. Jump in his truck and drive to the McKenzie Airfield in Grapeseed.
Get your plane in the air and head for the way point.
Follow the cargo plane, but stay low. You should be so low you are scraping the tree tops. If the ground gets lower, compensate by dropping your altitude.
Ron will constantly inform you when your flying too high, listen to him. If you don't, the military will shoot you down and you will fail the mission. You also need to avoid flying over Fort Zancudo or risk being shot down. Stay over the swamps until you're over the ocean.
Once you clear Fort Zancudo airspace. Gain altitude and get as close to the plane as you can.
Head directly for the plane's cargo door and fly right into the door of the plane. Once you're close enough, a cut scene will finish the rest for you.
Now shoot your way to the cockpit.
Take cover on the first crate and wait for enemies to come to you. Be careful of the falling vehicles.
Once clear, head for the cockpit and kill the pilot.
Turn the plane around and head for McKenzie Field marked on the map.
Eventually 2 fighter jets will show up, just ignore them.
Once the fighter jets open fire, jump from the plane and parachute to safety and the mission ends
To get gold:
- Accuracy - Finish with a shooting accuracy of at least 80%. Use auto aim on the enemies at the rear of the plane.
- Four Wheel Flier - Exit the cargo plane in one of the trucks in the back of the cargo plane. Exit the plane in a vehicle from the cargo hold, then jump out on the way to the ground.
