Press a plane and draw its line · time stops while you draw
Planes fly in over the airport at night. Draw a line for each one into the green landing path. Let two get too close and your shift is over.
Press a plane and draw a line. Time stops while your finger is down. The plane flies along your line, then carries straight on. It cannot turn very sharply, so it cuts a tight corner.
The line in front of a plane is where it will really be: one dot for every second. A fast plane's dots are further apart.
To land a plane, draw it into the green landing path, the fan of light at the end of the runway, pointing roughly at the runway. It is caught, lines itself up and lands. That is the only way out of the sky: a plane that reaches the edge turns round by itself.
The runway is busy for 5 seconds after each landing, and the landing path goes amber. A plane that gets there too soon goes round again.
An amber line joins two planes that are going to get too close, and a ring shows where and in how many seconds. Draw one of them out of the way.
Too close is the end. Nobody crashes: the alarm goes while the two are still apart. But a tower must never let it happen, so your shift is over. Your score is how many planes you landed.
The little arrows on a name tag are how fast it is: one for a propeller plane, two for an airliner, three for a jet.
On a laptop, press and drag with the mouse. Esc forgets the line you are drawing.
The runway is called 36 because you land on it flying north, which is 360 on a compass. Real runways are named the same way. The planes are named after famous flyers.
