Marking the 170th anniversary of Giffard's inaugural dirigible flight

By Ruth Wilson, CIA Alternate Delegate for Australia and Member of the CIA PMR subcommittee

History and anniversaries make good companions. On 24 September 1852, Frenchman Henri Giffard, an engineer and inventor, attached a small steam-powered engine to a huge propeller to move through air in a dirigible or airship for the inaugural flight. Records show his flight covered 17 miles (27km) travelling at 6mph (10kph). 

Henri Giffard was 27 years old, and acclaimed earlier in that same year with inventing the steam injector.
