A CENTURY OF PROGRESS, CHICAGO
The Boeing monoplanes of United
Air Lines have ushered in a New
Era in Travel. With two 550 h.
p.
super-charged Wasp engines, they
have a high speed of more than
three miles a minute. They carry
10 passengers, 2 pilots, stewardess and cargo and can
climb, fully loaded, more than 1,000 feet per minute
and to 10,000 feet in ten minutes. They can sustain
flight on only one engine.
