5 O'Clock Charlie

For six weeks, an ammunition dump near the camp has been the target of a punctual but inept North Korean bomber pilot. Every afternoon at 5:00, he flies overhead and attempts to hit the dump with a single hand-thrown bomb. The pilot, nicknamed "5 O'Clock Charlie", has been so reliably unsuccessful that the denizens of the 4077th have begun a daily betting pool based on how far away from the target his bomb will land. Only Frank and Margaret regard Charlie as a serious threat. Frank gets Henry to request an antiaircraft gun, and Brigadier General Crandall Clayton (Herb Voland) comes to the camp to assess the situation. Clayton, who has placed the dump near the hospital so that the enemy will leave it alone, is initially skeptical of the need for a gun. When Charlie's next bomb destroys Clayton's jeep, though, he agrees to send one. Frank takes charge of the gun and begins to train three South Korean soldiers in its use, but Hawkeye and Trapper mock him and argue that the gun's presence will draw enemy fire toward the hospital. Prompted by the camp dentist, Captain Phil Cardozo (Corey Fischer), Hawkeye and Trapper begin devising plans to get rid of the dump and thus remove the need for the gun. They dye sheets with mercurochrome to make a target for Charlie to hit; after he misses yet again, they confuse Frank's men into aiming and firing the gun directly at the dump to destroy it. Charlie stops his daily raids, believing he has finally hit the dump, and the staff of the 4077th returns to their routine duties.
