Charles Collins holds the official record for this game with 1,781,000 points on June 27, 1986.

>>> TRICKS AND TIPS
-------------------
* In the early stages, try to fly as low as possible - this way the fighters will not shoot you, and you are low enought to shoot the ground targets without being shot. Since this only works when you're in the air, and not when you're on the ground, it only works well on levels 1 and 3.
* To ensure that the tank won't arrive when you're picking up hostages, barely tap the joystick up between each hostage. This will cause the helicopter to lift off a little and reset the timer that causes the tanks to arrive.
* On level 2, you can land on the water under the boat when dropping off your men and they will climb up the side of the boat. This stops the planes from coming down and shooting you.
