Police Comics #33 (1944)

Plastic Man's due for a meeting with the FBI top brass, but absolutely refuses to let Woozy sit in because he hasn't got top secret clearance. In his efforts to ask Plastic Man to let him in, Woozy throws a rock with a note attached through the window. This unfortunately allows the miniature remote-controlled fighter plane the meeting's all about to fly out the window (the inventor can't stop it because Woozy's rock wrecked the control box). Fortunately for the hero, Woozy recognized the hooded criminal who made off with the plane; he lives in the creepy old mansion behind Woozy's boarding house, and Woozy sees him coming and going all the time. One of the criminal's underlings suggests selling the revolutionary fighter plane to hostile foreign powers, but the boss angrily shuts him up, reminding them he has a much greater reason for stealing it. Plastic Man sneaks in, is discovered, and lured into a sealed chamber by the masked mastermind. He lowers the temperature inside to -50, freezing Plas solid. Woozy, still insistent on helping his friend, tries to get inside the mansion but finds all the doors locked, so he tries to climb in through a window with a ladder. In doing so Woozy knocks down the power lines, restoring the temperature inside the deathtrap. This means when the mastermind and his underlings come in to finish off Plastic Man, he's as malleable as ever. While chasing down the boss, parts of his body keep coming off. Finally Plas captures him, and the criminal tells his story: he invented the helicopter, but there was a gas explosion that mangled his body. By the time he was discharged, somebody else had patented the helicopter, leaving him with a manic hatred of all aircraft: "That is my destiny! To destroy all airplanes and all pilots -- until flying is a forgotten art!" They're at the police station by then, and Plas hands the demented villain off to the desk sergeant.
