THE AIRPLANE IS

A TRIUMPH OF MODERN SCIENCE

We are at the opening verse of the opening page of the chapter of endless

possibilities. — Rudyard Kipling.

Introduction.

In 1941 the Douglas Aircraft Company completed its first B-19

bomber — a huge airplane capable of transporting 28 tons of bombs

or 125 fully equipped soldiers and having a wingspread of 212 feet, a

length of 132 feet, and a height of 42 feet and 9 inches, which is equivalent

to that of a three-story building.

With a fuel capacity of 11,000 gallons, the B-19 can fly from Los Angeles to

London and back to New York. (Courtesy of the Douglas Aircraft Company.)

This monster airplane is the largest one ever constructed; although

the German Do-X flying boat carried 170 persons, its wing span was

only 157 feet, and it could travel only 114 miles per hour as compared

with the 210 miles which the B-19 bomber can do.

The real significance of this huge airplane is not so much that it may

make feasible round-trip bombing expeditions to Europe as it is that

the B-19 bomber represents a great many of the advances of modern

physical science and typifies the possibilities of the application of the

power of science when applied to warfare. The B-19 will also serve as

a testing-laboratory, which will give help in developing the cargo planes

of tomorrow.
