Evening star., 1934-02-25

pleted for Pan-American by Sikorsky
and Martin.
France last year made two expert
mental South Atlantic airmail flights.
On January 27 an Italian flying
boat left Rome for South America
carrying q load Of mail, landing at
Casablanca and Dakar successfully.
In forced landing on the Brazilian
coast, however, their plane was dam
aged.
Credit for the pioneering of the
South Atlantic must be given to Ger
many. The Graf Zeppelin service,
carried on for two years with entire
success, now has been augmented by
the most carefully planned and best
organized flying boat service across
the ocean the world has seen.
Flying Cows Described.
Cows, in life Of the most sedate
and terrestrial habit, in death are
taking to the air in roaring flight
at least in part. The portions of the
peaceful bovine which go a-flittering
| along the airways after the last
roundup include milk, blood, bones
and hoofs, hair, hides and intestines,
according to an aviation census of
COW parts made by United Airlines.
The flying portions of Old Bossy
were described as follows:
Mnk-From the casein content of
milk Is made the strongest kind Of
glue, used extensively in airplane
building
Blood-Aso used for glue, chiefly in
connection with production of air
craft plywoods.
Bones and Hoofs-Used for the
manufacture Of what is known as
hot glue" which also finds its way
into airplane construction.
Hair-Made into felt for padding,
sound insulation, cushioning against
vibration and for other purposes.
Hides-Used far seat coverings,
straps and lacings.
Caecum-The fine intestinal skin,
commonly known as "goldbeaters'
skin" used in airship gas cell con-
struction.
Airplanes Create Clouds.
An airplane travelling through per-
fectly clear sky may leave clouds in
| its wake under certain atmospheric
conditions, it is said by air trans
port officials who have had their
attention attracted to this unusual
| phenomenon.
On rare occasions, particularly at
high attitudes, it was pointed out,
the turbulence caused by the pro-
peller and the passage of the plane
through the air may result in partial
condensation of moisture in the air,
with resulting cloud formation.
However, 1t was said, the extreme
| tenuousness of such clouds and the
| relatively small area which they
cover make them very uncommon
sight.
Cloud formation behind high flying
| Army pursuit planes at very high
| attitudes Is an occurrence which has
caused the Army Air Corps a great
deal OF trouble. In this case the
freezing Of water vapor contained in
the exhaust discharge from the motor
Is responsible for the telltale cloud
which marks clearly the positions of
high-hying pursuit planes otherwise
invisible to the naked eye of ground
Observers
Air H0Stesses Small.
The average airline stewardess, or
hostess, is young, petite and brown
haired, according to officials of Amer
ican Airways. She is % years old,
weighs ITO pounds and stands 5 feet
inches in height.
| Brown hair is predominant among
the flying hostesses, check of the
stewardesses made by officials of the
line disclosing the fact that the girls
with brown hair outnumbered by
more than four to one the girls in
their profession with hair of other
colors.
There seems to be no definite
choice between brown and blue eyes,
it was said, the division between the
two being almost exactly even.
All the stewardesses are graduate
nurses Of current registration.
