MARKS new ERA
IN j. S. FLYING
All Metal Plane Will RevoIutionize
Aircraft Design and
Construction.
BIG ADVANCE IN SCIENCE
FraiI Spruce and Linen Ship That Did
Its Bit In War and Has Been Used
In Commerce Will BE Displaced
by All Metal Type.

New York.-The presence in Amer
lea Of John NJ. Larsen's JIG all metal
monoplane will completely revolution
lie aircraft design and construction,
according to statements made here by
leading airplane manufacturers.
The frail spruce and linen ship that
did It's bit in the war and that has
been used successfully, though pre-
cariOusly, in commerce will soon be
displaced by the sturdy all metal type
brought out after the war by the
Germans, almost every aeronautical
expert who has witnessed the per-
Torrance of the JL-6 agrees. One
American manufacturing company has
already announced Its intention of
disseminating operations.
The War Plane Passes.
There Is little comparison between
the JIG and the old type plane.
The only type of airplane that was
successful prior to the JL-6's appear
ance was the wood and linen biplane.
The wing beams. the long fuselage.
the engine bearers, the struts, the
NCiS hiuoc ~ UAth0A
spruce or ash and the wings were
covered with Irish linen. The fuse
iage between the wings gave support
to the panels. 1t was strong ship;
only a cyclone or crash could warp
the wings around the fuselage.
But 1t appears as fragile and dell
cate as a china vase beside the JL-6.

metal wing spreads from each side OF
the body, wing that measures eight
or ten inches in thickness at the lead
ing edge, and has trailing edge as
thick as the blade Of your knife. There
are no interwing struts to offer wind
resistance, no control horns on the
ailerons, no flying or landing wires,
no control wires free to the wind. II
has been said that the flying, landing
and control wires Of the old type ship
cut down its speed by as much as
twenty five miles an hour.
Wings Survive Side Slip.
The wings of the JIG are so rigid
that only head on crash will in1ure
them. One plane that side slipped to
the earth was Immediately righted
and flown away after a new propeller
had been put on. Not even the fuse
lage to which the metal panels are
attached was injured. Eighty-five
men have stood upon the forty-seven
foot spread without causing any III
effects.
The body of the plane contains
luxuriously furnished compartment
that will seat In upholstered chairs
six people. Two pilots may be seated
in the control compartment. The mo-
tive power is furnished by 100 horse
power Mercedes engine. 1t requires
five gallons of gasoline to fly 100
miles. Present aeronautical motors
require from ten to fifteen gallons for
that distance. The motor Is almost
silent, compared to the deafening roar
of the Liberty. A conversation can be
carried on In the cabin with the motor
wide open.
According to Mr.. Larsen, the JL-6
represents the greatest step forward
In flying in all time. He has pur-
chased all American rights, from the
Junker company of Germany, which
first perfected the all metal plane. 1t
was from an all metal battle plane
that the boche shot down Maj. Raoul
Lufberry In the most heroic air battle
of the war. Dr. Hugo Junker, German
engineer is the original designer OF
the all metal ship.
