engine was brought about through the

cooperation of more than a score of

engineers, who pooled their skill and

trade secrets in the war emergency, working

with the encouragement of the Aircraft

Production Board, the War Department,

and the Bureau of Standards. The story

of the production of this engine is a

remarkable one. Probably the war has

produced no greater single achievement.

"An inspiring feature of this work was

the aid rendered by consulting engineers

and motor manufacturers who gave up

their trade secrets under the emergency

of war needs. Realizing that the new

design would be a Government design

and no firm or individual would reap

selfish benefit because of its making, the

motor manufacturers nevertheless practically revealed their trade secrets, and made

available trade processes of great commercial value. These industries have also

contributed the services of approximately

200 of their best draftsmen."

He stated that parts of the first engine

were turned out at twelve different factories, located all the way from Connecticut to California, and that "when the parts

were assembled the adjustment was perfect

and the performance of the engine was

wonderfully gratifying. Thirty days after

the assembling of the first engine preliminary tests justified the Government in

formally accepting the engine as the best

aircraft engine produced in any country.

The final tests confirmed our faith in the

new motor." He also asserted that the

parts of the motor had been standardized

and that production could proceed with

great rapidity in many factories.

Subsequent developments showed beyond question that in reality the Liberty

Motor was still in an experimental stage.

A great number of changes had to be
