Pershing Will
Have 80OU.S.
Planes in July
Machine. \Equipped With
Liberty Motors Prove To
Be Fastest in World
By Theodore NJ. knappe,

DAYTON, Ohio, May 1.-THE. one
thousandth Liberty motor was COM
pleted yesterday. To-day the first
plane designed especially for the Lib
erty motor, few with marked success
at Wilbur Wright Aviation Field. To-
morrow the Tooth De Haviland plane
equipped with Liberty motor will
be shipped to France.
Quantity production of "De Haviland
q" fighting planes, equipped with Lib
erty motors, has been attained. With
the shipment of the one hundredth
plane the daily output Of De Havilands
from the DaytonW Wright factory goes
to eight day and may within week
Jump to fifteen a. day. The shipment
OF completed De Haviland planes, how
ever, tells only a part of the story, as
with each hundred assembled planes
there go enough spare parts to suffice
for the assembling of seventy-five more.
The American Liberty Motors in
American De Haviland planes are al
ready in the hands of American avi-
ators In France in considerable nem-
Der, although they have not yet made
their fighting debut. At the present
rate OF production and shipment there
should be near 800 of them in France
in July instead of the thirty-seven that
Senator'S talk about.
France, England and Italy are now
vying. with each other to be The first to
get Liberty motors in quantity. A
number of the motors are already at
French and English factories. England
has just doubled her order, and the
number spoken for by the three big
Allies is we'll into the Ave figures. The
total number of motors now on the
books of the manufacturers approx
mates 10000. And vet sclf-constituted
aeronautical authorities are still talk
ing about the Liberty motor being a
failure. In fact, the much maligned
motor is all that was most optimisti-
cally claimed for it.
The De Haviland Four. with the
Liberty Motor installed, is the fastest
flying machine in the world. It can be
seen daily at the field of the Dayton
wright Company flying circles around
the Rolls-Royce in the same sort of
plane, and the Rolls Royce is admitted
ly the most powerful aerial engine
that the Old World has produced.
French, British and Italian officers
are loud in their praise of the wonder
full motor, which on a weight of 825
pounds IS developing from 426 to. $50
horsepower as against $50 horsepower
and weight of 1000 pounds for the
Rolls Royce.
Forget Gutzon Borgium and the ouid-
nuncs of the Aeronautical Society. for
get all the trying delays, forget all the
amazing mess of libel and Grass ieno-
rance that have dimmed the splendor OF
a grea. American engineering achieve
ment, and take this reinsurance To
yourself: The Liberty motor is as great
q reinforcement to the armies Of the
air as the American infantry is to the
Allied armies. Even now it is being
shipped at rate nearing a hundred q
week to equip English De Havilands
and French Breguits with power that
will give them tremendous superiority
over the best the Germans have.
True, America was late, but America
has not failed. The schedule called for
5000 completed Liberty motors by
March /. We have 1000 in the middle
OF May. We are late, but we are on
the eve of tremendous production and
We are giving the Allies what they
wanted Of us-the monarch motor Of
the air.
