The Spy Plane is a support power which can reveal the shroud and fog of war at any spot on the map for a short period of time. The player must have an airfield to unlock this support power.
The spy plane can be used once every 2 minutes and 30 seconds, and cannot be attacked.
The spy plane can see through a (mobile) gap generator's shroud.
A player can tell when an opponent has used the spy plane, because it can be seen visually.
