The Brodie System was invented during World War II. A pilot could take off or land with the aircraft hooked to a trolley that ran along a cable. On landing, the trolley provided braking for a smooth stop. The cable and trolley could be rigged on very short jungle fields, or even on ships. In this photo, riggers hook this L-5B to the cable before take-off. Captain James H. Brodie, inventor, is on the left.
