On July 8 2006, after 33 years of research and 11 years of construction and testing, pilot Sansenderson accelerated the Flapper (так назвали самолёт с машущим крылом Jeremy Harris и James DeLaurier) down the runway. It took off and flew majestically - for 300m and a whole 14 seconds. Then a small portion of the left wing's trailing adge buckled and caused the twisting action of the wing jam, reducing its trust and lift. As a result, the landing was inelegant, with the aircraft pivoting around and collapsing its nose wheel.

But the team was ecstatic. After all, their Flapper had flown further than the Wright brothers' first flight of 36m in 14 seconds.

Does flapper has future?

Although ornithopters aren't likely to ever carry you and 499 other people to the other side of the world on a long-haul flight, they do have many advantages that might make them more common in future than you'd imagine. Ornithopters work by accelerating a large mass of air to a low speed; in contrast, jet engine accelerates a small mass of air to a high speed. This means ornithopters are potentially much quieter and more efficient that current aircraft. Given time, it's possible that quite, fuel-efficient ornithopters may one day play a significant part in the light aviation scene. They would also be suited to such work as long-range patrols, cruising along borders, watching traffic and patrolling coast lines.
