The ship which is 130 feet long and has a wing spread of 96 feet is able to lift 85,000 pounds. The unique flying machine will be powered by five 420 h.p. engines and will have a top speed of 135 miles an hour. The ship will carry 80 passengers and their baggage more than 4,000 miles without a halt.
