Jack Binns, Wireless Expert, Says Only End =,
War Saved Capital; Gives First Account Of !,
ventions That Baff1ed the Germans in the A.

tion is equally remarkable. II :.

a Handley-Page while flviny ~

than ten minutes. "%
The manner in whici, these oh...
tions are taken is as follows. os
the two coils on the machine : U
able through complete circle NJ.
coil Is moved until it receives s;sn.,.
from some well known wireless ' =.
tion in Europe. The direction of n.
coil gives the true bearing of that M.
ticular station after allowances b,s
been made for certain well known .,
charted errors, such as maenetic A.,
alton of the compass and ousdrsn,,
error of the aeroplane.
Used by Bomb Droppers
The angle of the station to the h.,,
ing of the machine is then worked -.
on chart, and the resulting line d,,u,
clear across the chart. When tb;s !.
completed the coil is turned aronns
until some other well known Stain, !,
heard. The same process is comple.s3
and the point where the two lines c,o,
is the exact location of the aero,l,,.
IN latitude and longitude above Il.
earth. The whole apparatus with .ss
exception of the coils can be carrjei IN
one hand; and the coils while bpll,,
have very little weight. 3''
Another remarkable feature ~ M,
! invention was its application to n,
big bomb dropping aeroplanes ,hs
ralded German cities. In this ras
there was variation in it's utilization
The coils were fixed rigidly in the ma
chimes, which then pointed themselye
bodily at wireless station situated 5
the point where they wished to 90.
In other words, German wireless vta
tlons directed British bomb droppf
aeroplanes to their cities withou
knowing it and over the shortest DOS
sihle route. The wireless stations bs.
of the British lines took care of thsi
return.
Telephones on Aircraft
Next to the direction finder the d.
velopment Of the wireless telephone d
aircraft has been the greatest achieyl
ment of the radio experts during I'll
war.
All the day and night bombil
squadrons were fitted with it |.
utilization brought success to boms
ing raids by eliminating all confusN
and enabling the squadrons to resA
their formation under all condition;
The squadron commander sitting il
his machine would issue orders in 81
ordinary tone that was easily heard
| above the roar of the powerful engines.
while the machines were rushing
through space at the rate Of a mile
every thirty seconds.
If, through unforeseen circumstances
a machine got separated from the
squadron it could rejoin By means o.
instructions given through the air b.
the human voice up to any distance
within twenty-five miles.
This wonderful invention was slsl
utilized in scout work. All the Brlsts
scouts were equipped with il.
They would sit above the cloue
watchfully waiting. Immediately.
German scout appeared the srtllsfi
cooperation machine would wireless
the fact to the aerodrome. li'
operator on duty at the 'drome Tou'
then talk into a telephone transmlta,
and ten seconds later the Bristol WOLF
swoop down through the CLOUDS upe'
its unsuspecting prey.
Tipped Foe Troop Movements
One of the 1918 developments vi
the long distance wireless telegfsp
sets for aircraft. With these machhs
engaged in patrol work HUNDREDS I
miles back of the German Lines eous
communicate instantly wlth assa a.'
quarters any distance up TO 4eO mis'
Not only this, but they could reesn
srecial instructions instantly 1--WE
headquarters.
The moment the German coHf1',
BEGAN to move troops in the bsa
areas the fact was known in all hsa
quarters in the British army -
All this was done from spec !
the sky, from an aeroplane ia'
enough to carry only TWO men: a. :,
Such is the brief outline OF sns = !
markable DEVELOPMENTS Of wireless
aircraft. It is the keynote OF Su''''
for commercial aviation.
