Mac ATC is a simple air traffic control game in which the object of the game is to land as many planes as possible without any planes crashing into each other. There are helicopters, light aircraft, business jets, medium jets, jumbos and concorde all trying to land at the same time. Just to add to the chaos, occassionally the Red Arrows will fly into the air space and you need to direct them away from the planes as quickly as possible. You may also create your own airfields and drop them into the airports folder.
SkyChart III is a planetarium and telescope control program that shows the sky from any location, past or future, on Earth or beyond.
