After tests on land, the system was first tested in September 1943 for shipboard use with an installation on the motor ship . Staff Sergeant R. A. Gregory made ten good takeoffs and hookups with a Stinson L-5 light plane. During the Battle of Okinawa, L-5s operated from an LST using the Brodie landing system which allowed a light aircraft to take off and land without a flat surface by snagging a wire hung between two booms. One of the L-5s that used the Brodie system off Okinawa is now on display in the Boeing Aviation Hangar facility of the Smithsonian's NASM's Udvar-Hazy Center annex at Dulles Airport just west of Washington, DC.
