Day Fourteen: First Human Flight

Over the summer I created over 35 achievement badges for the Withings Health Mate fitness app.

Day fourteen is the first human flight.

“The modern era of flight lifted off in 1783 when two brothers demonstrated their invention, the hot-air balloon, before a crowd of dignitaries in Annonay, France. Joseph-Michael and Jacques-Ètienne Montgolfier, prosperous paper manufacturers (a high-tech industry at the time), began experimenting with lighter-than-air devices after observing that heated air flowing directed into a paper or fabric bag made the bag rise.

The Montgolfier brothers built a balloon made of silk and lined with paper that was 33 feet (10 meters) in diameter and launched it — with nobody aboard — from the marketplace in Annonay on June 4, 1783. The balloon rose 5,200-6,600 feet (1,600-2,000 meters), stayed aloft for 10 minutes and traveled more than a mile — about 2 kilometers.

On Oct. 15, 1783, they launched a balloon on a tether with Jean-François Pilâtre de Rozier, a chemistry and physics teacher, aboard. He stayed aloft for almost four minutes.”
