Bombing Run is a control point ability in Fortress: Destroyer.

The player selects a target line and then a plane flies over, dealing 121 thermal damage, several times rapidly, to enemies near the target line. It can be noted that the plane looks like the Dart Storm from BTD 5, which is modeled after a B-12 bomber.
