At the Junkyard level, there is a white airplane that circles the arena. Shoot it down with a fire or homing missle. If you are successful, a message would read "Jet plane has fallin" or something like that. After that happens, drive to the LOWEST part of the arena where the plane has crushed and formed a tunnel. Go through the tunnel to where you see something like a support beam gen. Shoot the white control panel.

This one takes a lot of skill. I advise you to turn on "Infinite Health and Turbo". At the Freeway level. go towards the large Construction site with 2 large cranes. The one on the right has a swing arm with a pipe and the left one has a crate. The left one is the one you want to shoot at. Between the road and the cranes there is a ridge. Aim your car towards the elevator or control box and blow it up. A crate will lower to the yard. Drive to corner where the crane is. Blow up the crate. Hint: If you Hold R2 and aim your car towards the box, then fire a missle towards it.
