Only the pilot who drops down to enter the runway approach can see new-type portable landing lights put into use by the United States Army Air Forces. In fact, they cannot be observed even from a low-flying plane ditectly overhead. Each hooded light looks like a plump duckling squatting on the ground with a light in its beak. Its beam does not shoot across the landing lane but parallel to it, green lights being arranged at the entrance and amber at the exit. The system calls for steadiness and an accurate approach, but landings are smooth and safe. The lighted area is 400 feet wide and 3,200 teet long. The light standards and the portable power plant can be set up ready for use in 30 to 40 minutes to convert any smooth plot of ground into an emergency night landing field. They can be “rolled up” ready to be moved in ten minutes.
