Additional details on design, construction, and performance of the great Douglas B-19 bomber are now available. Scheduled to be ready for flight testing late this year, the big bomber now has a crew of 500 engineers, technicians, and mechanics working in three eight-hour shifts to apply the finishing touches to this one airplane. Construction has been underway for nearly four years.
Some 9,000 individual drawings were made during this time, sufficient to cover 4 acres. Nearly 3,000,000 rivets have been driven and 10 miles of electrical wiring and 2 miles of control cable installed. Engineering time on this project will total more than 700,000 man-hours, construction time 1,250,000 man-hours, and test and research 42,500 man-hours. When taken over by the US Army Air Corps the B-19 will serve as a flying laboratory for assembling structural and tactical information.
