First successful helicopter

17sep14sikorsky

On this date in 1939 Igor Sikorsky piloted the first successful helicopter which he also designed. While he was a pioneer in vertical flight he was not the inventor of the helicopter. However, his improvements of a single lift rotor and a tail rotor made the craft controllable. This prototype led to the first production helicopter.

Although this test occurred in Connecticut, it influenced flight around the world.

National Aviation Day

17aug19aviationDay

National Aviation Day, August 19, celebrates the development of aviation.

“The holiday was established in 1939 by Franklin Delano Roosevelt, who issued a presidential proclamation which designated the anniversary of Orville Wright’s birthday to be National Aviation Day (Mr. Wright, born in 1871, was still alive when the proclamation was first issued, and would live another nine years). The proclamation was codified (USC 36:I:A:1:118), and it allows the sitting US President to proclaim August 19 as National Aviation Day each year, if desired. Their proclamation may direct all federal buildings and installations to fly the US flag on that day, and may encourage citizens to observe the day with activities that promote interest in aviation.”
