Just Plane Dumb

The military commander had grown increasingly anxious over rumors of an impending air strike from the enemy. So, he summoned a corporal. ???I want you to climb that mountain and report any signs of a military activity.???

The corporal trudged up the mountain. As soon as he crossed the ridge, he saw a squadron of planes heading their way.

???There are many planes coming!??? he promptly radioed back.

???Friends or enemies???? the commander demanded urgently.

The corporal again lifted his binoculars to the sky. ???They??™re flying very closely together, he replied. ???I think they must be friends.???.
