They weighed less than 800 pounds and were completely unarmed. Yet these cloth covered spotter planes did more damage and created more chaos than any other aircraft used in WWII. Flying low and slow to see all enemy movement, the L Birds would call in artillery fire to rain death and destruction on their targets. Thanks to an innovative suspended landing system that hung above trees and over the sides of ships, pilots could land and take off without ever touching the ground. This landing system saved the US Navy from possible annihilation in Okinawa and earned the L Bird a reputation as the most deadly plane used in WWII.
