Solar Impulse has successfully landed in Abu Dhabi, completing a round-the-world trek that began in that same city in 2014.
The last successful leg of the trip was piloted by pilot and mastermind behind the Solar Impulse journey, Bertrand Piccard.
Piccard and fellow pilot André Borschberg alternated flying duties in the super-lightweight solar-powered airplane during their epic 17 leg journey around the world. They undertook the journey to show that solar power is a viable clean energy source both for future transportation options and for society as a whole.
The journey was delayed on several occasions due to bad weather, sickness, and battery trouble stretching out the journey.
