Ballooning Primer
A general background on ballooning technology.
Balloons
are the oldest manned aircraft with both buoyant gas ('gas balloon')
and hot air balloons both making their debut in 1783 in Paris, France.
Both types of aircraft made their first manned flights within 2
weeks of each other. Unlike the early flights of the Wright
Brothers, often conducted
with few observers, the early manned balloon flights were witnessed by
thousands and thousands of observers because the aircraft is VTOL
and slow, so
oberservers could safely be accomodated near the aircraft.
Gas
ballooning became the dominant ballooning technology for over a century
after 1783, with the age of modern hot air ballooning starting in the
early 1960's in the USA. Early gas balloonists used hydrogen gas
produced on site with thousands of pounds of acid and metal in reaction
barrels. Starting in the 1800's, the age of 'city gas' allowed
balloonist to fill their balloons with 'city gas' or 'coal gas'
(comprised of hydrogen, carbon monoxide, methane and carbon dioxide)
from a gas works.
The earliest membrane balloons were
celophane, pioneered in the 1930's by Dr. Jean Piccard.
Experimentation with polyethylene in the 1950's and 1960's lead
to the precursors of the modern plastic membrane balloons used by
scientists and researchers today.
