Paratreed -- Bridge sections descended satisfactorily during an engineers' paradro maneuver in Germany, but this giant parachute persisted in making like a tent. Yank soldiers try to free the huge silk umbrella from its tree trap after removing sections of a bridge dropped near the Rhine in the Darmstadt area. The combat engineers' maneuver enabled troops to bridge the Rhine River from east to west for movement of tanks. March 15, 1952. (Photo by AP Wirephoto).
