The Graf Zeppelin Cloud "Car" (also called a Spy Basket) : "About 300 feet down, while the winch was allowing the cable to unwind slowly but steadily, the tail of the car became entangled with the wireless aerial. It caught the car and tilted it upside down. The cable meanwhile continued unwinding from the winch above and was beginning to dangle in a slack loop below Strasser, who only saved himself from being tipped out by clinging to the sides of the car with a deathlike grip. Suddenly the aerial gave way, sending the car and Strasser plunging down until it brought up at the end of its own cable with a sickening jolt.
