AERONAUTICS: Biggest

Nearing completion last week at Bristol, Pa., were four 20-passenger, all-metal monoplanes, to be the largest in the U. S., smaller only than a few German planes.

They are equipped with luxurious trappings, hot and cold running water, sleeping compartments, radio sets, spacious windows. The 90-foot wing spread will lift, beside fuel and passengers, 1,000 pounds of baggage. The three Wright Cyclone motors will propel this load at an average 130 m. p. h. for four and one-half hours, could if necessary attain 155 m. p. h., climb 16,100 feet. Edgar M. Gott, president of the Keystone Aircraft Corp., has for the last two months kept the construction of these monsters a secret.
