that traverscs the air an "airshlp'

employed. They say. that all balloons

Obsolete but originally used to
designate a non-rigid airship, driven
by an engine installed in an airplane
fuselage slung beneath the gas bag
The word "hydroplane,' has ofteh
been misused in referring to a sea

According to the recent published

of craft designed to navigate the
air and is divided into 'aerostats ana
"airplanes." Aerostats comprise light-

by it's buoyancy, they include 'air
ships" and balloons
