A spaceship pilot works hard for a living in Jason Holiday's game

Your expert skills as a docking pilot will certainly stand you in good stead, when you carefully guide your space shuttle on to the rugged terrain of an unknown planet.

This almost foolhardy mission is entirely in the interests of science. Two boffins have decided that they must alight and examine the area. Wary of dangerous chemical substances that may cover the planet's surface you intend to land on one of the two landing pads. This is easier said than done, especially as one is at the bottom of a very deep crevasse. If you choose to land on this pad instead of the one at ground-level you are awarded a bigger bonus. The risk is optional!

You cannot land at a speed greater than -5 or your ship disintegrates, so while aligning yourself with the base you must use your thrust to brake your descent, which uses up fuel. The contents of your fuel tank are therefore displayed all the time, as is your speed.

It seems that your arrival is not welcome and you are set upon by a series of missiles which are on course around the planet's surface. You are also bombed from above.

There are four levels of difficulty:

Level 1 is relatively easy with less bombs and missiles than level 4. There are eight drift speeds (the speed at which you advance, and as you complete each stage you automatically move up a level till you reach the most difficult level.

Successful landings could result in your name being entered in the 15-name long hi-score table.

Enter the program in order in three parts (Lander 1-3), saving the program at each stage.
