Shoot down 10 enemies with machine guns in "Throttle."

Mission 13: Throttle

At the start of this mission you will be piloting a jet. For this trophy, you need to shoot down 10 enemy jets using the machine guns. You don't want to touch the missiles at all. There are plenty of jets you can shoot down, just take the whole canyon section slow as once you exit the canyons you also exit the jet. Don't use your afterburners, just take it slow. The machine guns auto lock onto enemies when you get near them so it makes the trophy even easier. Once you have shot down 10 with machine guns, the trophy will unlock. Here is a visual walkthrough if you are having trouble:
