Herr Hentzen, a student flyer of the
Hanover Technical School. late Satur-
oay afternoon in the glider tests on
tho Rhoen mountains established a
1Icw glider record by remaining in
the air two hours and ten seconds.
Hertzen used the same single-deck
sail plane in which another student
named Maertens previously had made
:, hlght of sixtysix minutes. He
reached an altitude of 100 meters
above the summit OF the Wasserkuppe.
which Is at an elevation OF $50 meters,
and later mounted to height of zoo
meters. which he maintained through
. out his uniform flight. cruising with
a wind velocity Of from seven to nine
miles.
When the wind subsided Hentzen
attempted a straightaway flight In an
effort to capture a special prize OF
100000 marks. The glider landed at
the same spot where MacrtenS came
down Friday.
Other students Compete.
A group of Darmstadt students also
competed, but none of them attained
the records OF the Hanover flyers:
Both groups Of competitors used sail
planes, which are not unlike motor
driven planes. Both types are single
deckers, in which the flyer Is seated
in the body OF the plane. which Is
beneath the deck, and terminates in
double decker sail planes arrived on
the field today. Their surface meas
urements are twenty-seven and
thirty-six square meters.
German sail plane experts are en-
thusiastic over the records made by
Hentzan and Maertens. They declare
that while the French records at the
C7emont Ferrand gliding contests
are being calculated in minutes the
German records already are being
man achievements are cited as splen-
did vindication of the theories ad-
Vanced by Gustav Lilienthal. pioneer
constructor OF the motoriess plane.
Contestants Total Fifty-Three.
Fifty-three contestants have enter
cd for the competition, the start OF
which was delayed through unfavor-
tive sail planes have reached the
aviation field. Most of them show
marked constructional improvements
over former types. Their wind and
air resisting qualities have been re-
duced to a minimum. based on ex-
periments made on the air currents
in the Goethningen wind channel
Some Of the new planes are OF the
hird-shaped type. The new single
deckers have been given wider ex-
pansion of plane surface and have
movable planes and new steering de-
vices. The structural improvements
have brought forth favorable results
at the outset of the present contest,
for all last years records thus far
have been beaten.
No news has been received by the
MANAGEMENT of the meet regarding
the prospects of the entry of Edmund
Allen. who Is flying at Clermont Fer
rand under the auspices of the Mas
sachusetts Institute Of Technology.
Lilienthal was one of the early
students Of aviation who went deep
is into the problem of maintaining
equilibrium. Natural air currents
were utilized and the aviators OBJ
5ained balance and stability through
the movement of their own bodies
or through the action OF portions Of
their aircraft which they had under
In = machine with bat wings and
depending upon gravity as its motive
power Lilienthal made more than
1000 glides safely, but finally was
killed In 1S9e when his machine was
overturned by sudden gust of wind.
