A PERFECT WIRELESS TELEPHONE Is
W. AMERICAS GREATEST WAR SECRET

Held the squadron went through sew
eral maneuvers. forming right lines
and left lines, breaking OF In differ
ent directions and swinging back into
line again. Everything was done with
perfect precision.
Colonel Culver explained that Major
Rossell was giving every order by
word of mouth and that every man in
the fleet was getting orders at the ex,
act instant.
Nov If you want to you can stand
here on the ground and hear Major
Rossell give these orders, and you car
at the same time that you hear them
see them carried out" said Colonel
Culver.
He led us to n small shack from the
roof of which dwarf aerials project
ed, put receivers over our airs, and
u moment later l heard a strong voice
say:
by the right flank" Then there
was a second of hesitation, followed by
a stentorian, long drawn'out 60" and
away off in the eastern heavens | saw
the long line of small dots swing of
to the right, and for the moment, out
of sight. And those words came from
Major Rossell, spoken In an ordinary
tone, 6,000 feet in the air and fully
Ave miles from where l was standing.
And | was Informed that II would
have been Just the same If he had
peer further away. However, the
range of the e wireless telephone
is one of the secrets that the division
of military ae%ronautics Is not reveal
ing just now.
For more than an hour l heard
Major Rossell put his squadron
, through a drill and at the same lime
that | heard his orders l saw them
executed. These things took place
while these 10 airplanes were rushing
along ut more than n hundred miles
an hour at an altitude ranging from
1000 to 5000 feet, and with the man
giving the order fully two miles from
the nearest of his men.
!, The apparatus used for wireless
t~elephonlng is so simple and so com
, pact that one would never notice
either the transmitting or receiving
devices on an airplane unless his at
: tention was called to It. With thu
consent OF General Kenly, Colone
{ Culver gave me a great deal OF In
u formation about these devices and TIL
following facts are the first publishes
= about what perhaps is the creates
y invention of the war.
Description of Device.
The transmitting set consists OF
l power plant, a set box, Il transmitte
or %microphone and an antenna sy'

generator driven on the windmill pril
u clple by the passage Of the alrplan
through the air. 1t is placed SOM
s. where in the open, usually on the rul
ming gear or on one of the wings, an

ously as the airplane travels along.
81 The so-calledt set box receives III
power from the generator, converts

wires. which are connected as In Il
