Make it so the game will detect if a build is touching the terrain, the sea or anything at the surface (runways, aircraft carriers, etc) and shows it at the AIR-TO-GND (Air-To-Ground) radar.

For example when you spawn an AI craft at the Wright runway it will show up on the
AIR-TO-GND radar, and when it takes off the green indicator square will flash for 5 seconds and the craft will vanish from the AIR-TO-GND radar and show up on the
AIR-TO-AIR radar, the same goes for builds at the aircraft carrier.
