The incandescent lamp plays an i'm

less telephony from air fleet to land
battlements. A tiny lamp that can
generate one horsepower of energy is
used to receive the faint currents. and
Il larger one boosts the currents so
that the ordinary telephone apparatus
can receive them.
According to report 1t is common
occurrence for a young American or
French aviator now to be talking to
