HISTORIC AIRPLANES: Boeing
In 1925 Boeing produced its first transport
airplane, Model 40 (M-40), a single-engine craft. Its successor,
M-40A, built in 1927, was the first mail and passenger carrier.
The company's trimotor craft, the M-80, was produced
the next year. In 1930 the company introduced its streamlined
Monomail airplane. Although this craft was not produced in
numbers as large as the M-80, it represented another step
forward in the company's airmail transportation system.
Still enjoying a series of profitable airmail
contracts, Boeing was able to increase its passenger service.
The B 247 twin-engine airplane, built in 1933, carried 10
passengers, 18 fewer than the M-80 could carry. The smaller
passenger capacity represented an acknowledgment that passenger
traffic had not grown as quickly as hoped. Until it did, Boeing
and other airline companies continued to rely on airmail funds
for survival and growth.
