 During the war they saw airplanes land with lots of good materials, and they want the same thing to happen now.So they've arranged to imitate things like runways, to put fires along the sides of the runways, to make a wooden hut for a man to sit in, with two wooden pieces on his head like headphones and bars of bamboo sticking out like antennas—he's the controller—and they wait for the airplanes to land.They're doing everything right.
