to soaring activities by Arno p. Cam
merer, director Of the National Park
Service. The small amount of work
such as pulling of stumps, removal OF
rocks and little grading, necessary to
improve an already good site, will be
undertaken as part of the park pro-
gram.
1t is expected that the area will be
turned over formally to the United
States and made available as a glider
camp in time for the holding there
soaring meet, which for several years
past has been held at Elmira, N. Y.
American Leadership Shown.
The new American high-speed multi
motored transport airplanes are faster
than the new fast transport ships OF
three other nations, according to a
survey Just made for rn.eravia, Swiss
international correspondence on avia-
ton.
Only one Of the new American planes
the Douglas Del, is taken as repre-
sentative of several others Of the same
type, including the Boeing. Lockheed
and General Aviation twin-engine
transports.
For purposes Of comparison, the
Junkers Ju 52-3m, a low-wing canti-
lever monoplane; the Fokker F-20, a
high-wing cantilever type. and the
Dewoitine D-332, low-wing cantilever
monoplane, built in Germany, Holland
and France, respectively. have been Sc
lected. The Douglas is low-wing
cantilever ship.
The Douglas carries two engines, the
three foreign planes being trimotors in
each case. Despite this fact, the Amer
ican plane, though carrying as many
passengers, has greater speed than any
OF its foreign rivals.
The Junkers is powered with three
BMW Hornet engines, delivering q total
OF LOO horsepower. The Fokker, with
three American Cyclones, has a rating
Of 1920 horsepower. The French ship
with three Hispano 9V engines, is rated
at LIPS horsepower. fne American
plane. with its two Cyclones. has a
power rating of 1,400.
The Junkers carries Is passengers
the Fokker, 12; the Dewoitine, 8, and
the Douglas is listed as from IL to 18
Pay loads are given as 1858 pounds
Tor the Junkers, 4.224 for the Fokker
ALA for the Dewoitine and 3.4O0 for
the Douglas. Gross weights are listed
as 20, ,282 pounds for the Junkers, l9,47O
for the Fokker, 20,57O for the Dewoitine
and 1880 for the Douglas.
Speeds Are Compared.
The maximum speeds Of the four air
planes are given as 1878 miles per hour
for the Junkers, 1864 miles per hour for
the Fokker, 1864 for the Dewoitine and
206 Tor the Douglas. The cruising speed
ratings, which of course are more to the
point Tor air transport purposes than
the maximum, are listed at 146 miles
per hour for the Junkers, 1853 for the
Fokker, 1853 for the Dewoitine and 1876
for the Douglas.
The Swiss letter lists the landing
speed OF the Junkers as 81 miles per
hour, the Fokker as "a miles per hour
and the Douglas as SO miles. No land
ing speed is given for the French plane
The cruising ranges of the airplanes,
on single normal load of fuel, are de-
scribed as 932 miles for the Junkers
1,031 miles for the Fokker, 1,245 miles
TOR the Dewoitine and 1000 miles for
the Douglas. The German and French
planes have fixed type landing gears;
the Dutch and American retractable
types.
In the same letter there Is described
the flying wing" plane built by the late
Claire Vance, veteran American air
mail pilot who was killed when he flew
into California mountain In the fog
Vance's plane is said to have the great
est cruising range of any aircraft ever
built.
Powered with single Wasp engine
which gives a maximum speed Of 200
miles per hour and q cruising speed OF
160 miles, the Vance plane, 1t Is said
can take off with q gasoline load o1
1,200 q. 8. gallons, giving . nonstop
range Of 1900 miles, or about 1900
miles more than the recent distance
record set by the Frenchmen, CodoS and
Rossi, In their Bleriot ITO.
Mrs. Vance, the pilots widow, 4
ready to sell the atrplane to any COM
petent flyer who would be able to ex-
ceed the present record" says the Swiss
letter.
The Vance plane, a low wing type
built largely of wood, was designed with
the collaboration of Northrop an6
Douglas and of technicians Of several
American universities.
