Early on July 25, 1909, French aviator Louis Bleriot lifted off near Calais, France, and flew across the English Channel to Dover, England — the first airplane flight over that stretch of open sea. The crossing of roughly 22 miles took about 37 minutes.

He flew his own Bleriot Type XI, a fragile monoplane powered by a 25-horsepower three-cylinder Anzani engine. With no compass, he briefly lost sight of land before spotting the English coast and setting down hard near Dover Castle.

The flight won a £1,000 prize from the Daily Mail — and rattled a Britain that had trusted its waters for protection.

The feat made Bleriot a celebrity and turned his company into a leading aircraft maker. More striking was its symbolism: for the first time an aircraft had crossed a significant body of water and a national border, hinting that geography would never again shield a nation quite so completely.
