Kestrel was mounted on an aerostat and worked in coordination with a high-resolution full motion video camera.
The hull of the aerostat contains two parts separated by a gas-tight fabric partition.
The aerostat consists of four major parts or assemblies: the hull and fin, windscreen and radar platform, airborne power generator, and rigging and tether.
Initially the club was dedicated to promoting the spirit of aviation sponsoring early experiences with aerostat balloons.

Nowadays a balloon is an unpowered aerostat and an airship is a powered one.
A powered, steerable aerostat is called a "dirigible".
