Airplanes function rather particular when it comes to attacking units, facilities, or hexes in a tight space that is near an area where non proxy war entry is possible, such as ocean neutral tiles or neighboring countries. In this photo, you will see some of my tactical bombers in which do not want to take off from this airfield to bomb the nearby target.
If I send the airplanes inland, and then target the facility in question, the bombers will drop one bomb each and immediately return to base. They each have full fuel and supply loads and should in fact, orbit the target and blast it away.
