A aircraft completes 17-hour flight without fuel

The Solar Impulse HB-SIA prototype aircraft, which has 12,000 solar cells built into its 64.3 metres (193 feet) wings, attempted its first intercontinental flight from Payerne to Rabat in Morocco.After a flight lasting approximately 17 hours, the HB-SIA prototype has finally landed in Madrid-Barajas airport. The pilot, André Borschberg, made his way out of the cockpit, smiley and certainly happy to stretch his legs.This, and future international landings, are a good way for the Solar Impulse team to practice coordination and cooperation with international airports for fine-tuning of logistics, maintenance and facing challenges of air traffic patterns.
