field, the pots being buried so as to
leave the field clear of distractions.
The smoke clouds emitted from such
pots, it is claimed, are more sensitive
then wind cones or trees, and under GER
tain conditions are more visible than
any other indicating device, at least
during daylight hours.
Pots can be designed to burn old
crankcase oil. thus making use of
what ordinarily Is a waste product,
rather difficult TO dispose of, TO provide
a valuable aid to air operations.
Making the Skin Work.
There is a growing necessity, as de-
mands for airplane efficiency increase,
to make every ounce of weight count to
the utmost. The Army Air Corps, in
common with airplane designers, build
ers and users the world over, is at work
on such problems. One of them, on
which some degree OF success has been
attained, has to do with wing covering.
The conventional type OF all-metal
wing consists of an internal structure
of spars and ribs and covering. The
internal structure OF fabric-covered
wings, such as are used by the Army, is
designed TO take the entire load. The
covering of the wing Is so much dead
W
though the covering is in an ideal posi-
ton to contribute to strength.
AS a result of a number OF years Of
research under the direction of Capt
| Carl F. Greene, the Air Corps has an
! nounced q 55-foot all-metal wing has
been designed and built, in which the
covering of the wing is so disposed a.
to contribute a large share Of resist
ance to bending. This wing, 1t was an
/ nounced, is considerably stronger fol
/ its weight than the usual type Of can
tilever wing. even those of commercial.
! design in which wood and metal cover
ings have been used to carry some Of
the stresses.
New Air Line Planned.
The spiderweb of air transport lines
| connecting the National Capital witt
! the rest of the country will get another
/ spoke this month. when the Ludingtor
| Line inaugurates passenger service be.
| tween the Capital and Norfolk, Va.
! slashing travel time from an overnight
| trip by boat 10 approximately one houl
! by air.
The line is constructing q passenger
/ station at the new Norfolk airport anc
! enlargement of the landing area there
/ is in progress. Both projects are ex'
| pected TO be completed about October
! Is and trafic over the line will begir
as soon as possible after this prelimi.
nary work is finished.
/ In point of travel time saved. th'
! new line is expected to be one of thu
most effective of the many routes nov
4 serving the Capital. with the single ex
ception of the route TO Pittsburgh anc
! Cleveland. Inauguration of such serv-
| ice has been advocated for many
months by various civic and business
organizations Of the two cities.
Eastern Air Transport on october
! increased service over the southern enc
of its coastal line through the Capita
| by putting 18-passenger Condors intC
service on both the Atlanta and thu
| Savannah routes which unite at Rich
mond, Va. and Jacksonville, Fla. Tit
/ CondorS are flying the routes three
/ times weekly and the smaller King
