With the growth of the Air Corps
and the new General Headquarters
Air Force, greater stress is laid by
Army officials on the importance of
an active, well trained air reserve
and the creation Of the new division
is in line with the policy OF stimu-
lating reserve development to keep
pace with advances in the active
service.
The first annual Summer cruise Of
the Sportsman Pilots Association is
to be held July 22-24 In connection
with the All-American Aircraft Show
in Detroit, it has been announced by
Chester H. Warrington, vice presl-
dent of the association and president
of the Aero Club of Washington.
Warrington and other local pilots are
expected to participate in the cruise.
The cruise is to have its official
start at Lunken Airport, Cincinnati,
at am. Tuesday. July %. following
two days of entertainment for the
participants in Cincinnati. All par
ticipants are to fly to the Detroit City
Airport, attending the show that aft
ernoon. There will be meetings OF
the Boards Of Governors and directors
of the association on Wednesday, July
"a.
William r. Enyart, secretary OF the
Contest Committee Of the National
Aeronautic Association, will act as
cruise starter. The event is to be
flown at cruising speeds only and ac-
curacy of navigation is to be the
dominating factor Trophies will be
awarded at Detroit.
Ben King, national treasurer OF
the association and governor for the
District Of Columbia, who recently
established three world aviation rec
ords for light sirplanes. putting the
United States in the lead in the rae
with France for world aviation su-
premacv. is among the local pilots
expected to join the cruise.
Flving in the first Official contact
with the Navy in joint operations,
the 18th Pursuit Squadron. Wheeler
Field, Hawaii, and other squadrons
of the 18th Pursuit Group, during the
recent fleet exercises. found that un-
der ordinary conditions it Is easy
for an airplane observer to locate
a submerged submarine.
FLYING on a mission somewhat un-
usual for pursuit pilots-that of To-
eating submarines within attacking
range of the fleet-the Army flyers
found that, except when the sun was
very low, it was possible to locate
submarines running fully submerged
Many of the undersea craft were
located and reported by radio and
visual signals. The opportunity for
the Army pilots to work in co-opera-
ton with the Navy was regarded as
of great value professionally.
Medical problems resulting from
maneuvering and high altitude flying
of the type to which military pilots
in fast, modern combat airplanes are
subjected are being studied sys-
tematically by the Army Air Corps
in a new laboratory at its great
Materiel Division base at Wright Field
Ohio.
Fundamental research is being un-
dertaken into such problems as the
breaking of pilots teeth or the loss
of filings after high altitude flying
involving the use of pure oxygen. and
Of the "blacking out" experienced as
a result of the draining of blood from
the brain through centrifugal action
in high-speed turns and maneuvers.
The use Of oxygen even for normal
cross-country work is becoming more
common in the military service as the
altitude range of airplanes increases
Independent research was instituted
many years ago by the Army, but
many of the questions which have
arisen still remain unanswered. II
must be determined what is the most
favorable amount of oxygen to be in
hailed by the individual. the effect OF
its frequent use, its effect if used for
long periods at a time, whether gas
eous or liquid oxygen is preferable for
human consumption, the degree OF
concentration at which oxygen be-
comes poisonous to the system, the
oxygen requirements of sealed cabin
and a supercharged pressure cabin
and the effect of oxygen and carbon
dioxide mixtures at high attitudes.
The research into the oxygenation
and pressure supercharging of airplane
cabins at high attitudes is of increas-
ing importance to air transport lines.
