NEW YORK. Aug. 2i.-An
American motorless airplane. cap
able Of rising and alightlng upon
water. has been completed. and will
shortly be put through series OF
tests which. II successful will far
outdo any thing in the gliding line
where the flyers start from
mountain tops. Glenn II. Curtiss,
pioneer in the flying world said to-
day in an exclusive interview.
Praising German achievements at
Gersfeld. where an alrmsn remained
aloft hours and ten seconds I'm a
motorltss plane. Curtis said he ex-
pected shortly 20 demonstrate
glider In which the pilot literally
lifted himself by the bootstraps"
from the surface OF the sea instead
OF starting down a mountain side.
"Motoriess flight as demonstrate
ed In gliding tests IN the Rhone Val
ley. is In my opinion. not only an
interest, but a most useful develop
ment IN the realm of aviation" Cur
tiss said. But, while this Is mighty
good sport the real test comes when
a man tries 10 get his plane with
out any mechanical power, up on a
level stretch such as the surface OF
the sea.
If gliders without motive power
can remain aloft two hours on
rising current up "A mountainside. 1t
encourages us TO believe we may yet
learn TO soar like the Albatross over
the ocean.
Il. is this kind Of soaring flight
In which I am particularly interest
ed. having just completed a motor
less plane 10 start from and alight
upon the water.
The other line OF progress which
may be advanced as a result OF Gid
er practice Is the development OF a
low-powered and efficient airplane in
which the motive power may be an
engine OF or 10 horsepower. there

BERLIN. Aug 21 (Uni.ed Press).
Conquest with sail planes-motor-
iess airplanes-is the next objective
OF German science Judging from ex-
periments being conducted al Was
serkuppe where Herr Hentzen al
ready has remained aloft two hours,
ten seconds in such a machine.
This stands as the worlds record
but II may be smashed when the
Fokker gliders. two OF which have
just been received at the aviation
grounds are put into operation.
They have a greater wing spread
than the machine in which Hentzen
established the record.
Hentzen and Martens a fellow
student az the Hanover institute Of
Technology. associated with him in
glider experiments, are Of the opin-
ion that bnger sustained motOrless
flights are dependent only upon the
daring and skill Of the pilot In ay-
ing with a motorless machine 10 Is
necessary to ride the ascending air
currents. and TO watch the hills and
valleys below very closely. as as
cending and descending currents
are governed by the character Of the /.
ground above which they are found. I
Many strange stunts" have been
performed by the glider pilots, such
as covering considerable area and 4

and rising skyward in short jumps I

WASHINGTON. Aug. 21.-CUni-
ted Press)-A new and safer era in
aviation-lighter planes fitted with
motors OF much less power thus de-
-reasing speed and lessening dan
ser-was foreseen by Major General
Mason VI. Patrick. chief OF the army
lir service today, as possible result
of the two hour glider flight Of Ger
nan expermenters.
"The knowledge gained from the
5erman tests will have an important
1earing on the future of aviation, "
Patrick told the United Press
1T indicates that the aircraft Of
he future may be fitted with motors
II much less power that their speed
nay be correspondingly reduced.
With greatly increased safety both
n the air and in landing.
I'VE hardly believed that such
iight was possible" Patrick said.
For the past year we have been ex-
with such craft but few
3f us believed that one OF them
,ould remain in the air that long.
rhe success OF the Germans will
give added impetus TO our work.
"The two difficulties with aviation ,
oday lie in starting and landing. :
R reduction IN speed in both means
greater safety. The success Of the !
German experimerters indicates the
,oeeihflftv Of obtaining this"
