company" He also is credited with
the statement that 1.-The single-engined
aeroplane would only be used for postal
purposes and it would not be operated
on passenger services any longer"
The question as to whether two or
four engines will be used depends upon
airplane size and, considering the
present development of air traffic,
Lindbergh is quoted as saying he does
not see the necessity Of fitting more
than four engines on commercial air
craft"
Issue was taken with Lindbergh's
statement in Europe and it was pointed
out that a number of European lines
are to be equipped with new tri-
motored types in the near future.
Consequently" it was reported in
the Geneva correspondence, Opinions
are in contradiction in Europe and in
America To resolve such a question
of primordial importance it will GER
tainly be useful to hear the opinions
and experiences Of the European air
traffic companies and aircraft con-
structors"
To Study Polar Freaks.
Freakish weather behavior in the
Antarctic will be the subject Of study
by the two Washingtonians who will
accompany Rear Admiral Richard E.
Byrd when he leaves for Little America
about September 25 While one of
their most important duties for the ex-
pedition will be to provide weather in
formation for the airplane crews Byrd
will employ in his work of geographical
exploration, they also will make per-
manent scientific records for the Benefit
of the worlds meteorologists and
scientists.
The two Washingtonians- William G
Haines and John Grimminger-are spe-
cialists on the upper air conditions
which are so vital to effective airplane
operation and which apparently have
far greater effect on general weather
conditions than has been suspected in
the past.
| Haines is chief of the weather sta
| ton at Washington Airport and has
been associated intimately with aviation
| for several years. He was member OF
Byrd's previous Arctic and Antarctic
expeditions. 1t was he who forecast
| the favorable weather that made pos
sib,e Byrds flight over the South Pole
Haines and Grimminger hope tc
learn more about the unexplained tenn
perature changes in the Antarctlc
which have been observed to vary as
much as 40 degrees in two hours OF
less They will seek information con-
cerning the reason for tiny drops Of
water composing polar fogs remaining
liquid in temperatures many degrees be-
low the freezing point. Further in
| formation also will be sought regarding
halos around the sun which are thought
! to be caused by refraction Of sunligh,
! by minute ice particles in the air.
They expect to gather valuable in,
/ formation on how the weather arounc
the South Pole affects the climate Of
! the entire Southern Hemisphere. They
will study not only surface conditions
but also will make records twice daily
of upper air movements during the Pc
Rod Of their stay in the polar regions
Ten Woman Riggers Licensed.
Ten women in this country, one oi
them we'll known in Washington as an
exhibition parachute jumper, hold De-
partment of Commerce licenses as
parachute riggers, certifying that they
are qualified to repack and repair para
chutes There are total OF BIZ per-
! sons who hold similar licenses.
The task of the parachute rigger l!
! to unpack parachutes at frequent, reg
ular intervals, examine the silk canopy
