Historic Swiss Solar-powered Plane Crashes Into Sea

The experimental plane Solar Impulse 2, which completed a historic round-the-world trip in 2016 without using jet fuel, crashed into the Gulf of Mexico recently, its owner revealed. Flown by Swiss pilots Bertrand Piccard and Andre Borschberg, Solar Impulse 2 circumnavigated the globe in 17 stages, covering a remarkable 26,700 miles (43,000 kilometers) across four continents, two oceans and three seas, in 23 days of flying without using a drop of fuel. Three years after the globe-trotting flight, the solar-powered vessel was sold to Skydweller Aero, which converted the aircraft into a drone to carry out “controlled ditching,” the company said in a press release issued Tuesday. Skydweller Aero said Solar Impulse 2 took off from Stennis, Mississippi on April 26 but crashed into the Gulf of Mexico on May 4, AFP reported. “Ultimately, a record-breaking flight of 8 days and 14 minutes validates the reality of perpetual, solar-powered flight in a military mission-relevant environment,” the company said, in reference to a US Navy exercise in which the vessel was used. The US National Transportation Safety Board said it was investigating the accident.
