Airplane flight over waterIn 1910, the first U.S. airplane flight over water was made by Glenn Hammond Curtiss in his biplane over Lake Erie from Euclid Beach Park, Cleveland, Ohio, to Cedar Point, Sandusky, Ohio. At an altitude between 400 and 500 feet, the 70 mile trip took 78 minutes nonstop. Curtiss reported in the New York Times that he found that the "lake wind was not so steady as ocean trade winds. It was puffy the last twenty miles, and the riding then a little rough. Otherwise the flight was smooth." He delayed his return because of rain. The next day, flying back to Cleveland, he beat both the Lake Shore Limited train and homing pigeons, although it took longer than the first flight because he had to face strong winds. His return to Euclid Beach was greated by 20,000 people.«[Image: detail from cover of sheet music for the march "King Of The Air" dedicated to Glenn Curtis showing the aviator seated in front of the engine of his biplane with rear-mounted propeller.] |
