The very Question and Answer session that Q said Jfk jr was dead Q also said a plane it the Pentagon.
Any one with brains knows an airliner did not hit the Pentagon. The dictionary definition of Plane is simply a craft with wings that do not flap. Thus an unmanned craft could be a plane. So a drone or a cruise Missile could be a plane. Q was playing word games.
Q obviously plays loose with the facts for whatever technical reasons they want.
