VACUUM TANKS FOR WILLOW RUN WIND TUNNEL: These oil car tanks, converted from supplies intended for the USSR during the war, are pumped free of air to create the vacuum which draws air through the University of Michigan's supersonic wind tunnel at the Willow Run Laboratories. The air, which technicians hope to get up to speeds of 7,000 miles per hour, takes only 15 seconds to pass through the tunnel-- and two and one-half hours to be pumped back to the supply balloon.

ON SOUTH END: The hangar pictured above, a rear view, is located on the south end of Willow Run airfield. Built adjacent to the huge Ford bomber plant, which now houses the Kaiser-Frazer Corporation and Graham-Paige Motors, the airport contains six major runways besides the three hangars. The airport is located on an express highway, 30 miles west of Detroit, and has been idle since the war.
