A Century of Indoor Models

The story of Indoor Modelling:
Indoor models are perhaps the most graceful of all aircraft.
Models were first flown indoors in about 1907.
A century later, a competitive model with a wing span
of two feet weighs about a gram -- a third as much
as a US penny. The model will fly at about one mile an hour,
with the propeller turning once a second or less.
The wings are transparent, covered with a glistening
material of shimmering colors like a soap bubble.
The models fly silently, at the speed of a slow walk.
After launch, they climb steeply and slowly.
With enough available ceiling,
they can climb as high as a 15 story building.
Circling slowly so that they don't touch the walls,
they gradually reach their peak altitude.
There they will circle for many minutes.
Finally, as power runs down, they will descend.
In an ordinary competition, the flight time may be 10 or 15 minutes.
At a national or world championships held in a dirigible hanger
or similar large hall, the time may be more than half an hour.
The world record is more than an hour on a single flight.
