Solar Impulse 2 Completes Record Solo, Non-Stop, Solar-Powered Flight from Nagoya, Japan to Oahu, Hawaii

After a 118 hour solo, non-stop, solar-powered flight from Nagoya, Japan, pilot Andre Borschberg landed the Solar Impulse 2 aircraft at Kalaeloa, a small airport outside Honolulu, Hawaii.  During this flight,  Borschberg broke the world records for longest distance and duration for solar aviation, and the world record for the longest solo flight ever.  Solar Impulse 2 remained airborne for 5 consecutive days and nights, producing its own power with solar energy.

Key parameters of this remarkable, record-breaking flight is listed below:

Time of departure: 26 June 2015 18:03 UTC
Time of arrival: 3 July 2015 15:55 UTC
Flight time: 4 Days, 21 Hours, 52 Minutes
Distance: 7,212 km (4,481 miles)
Maximum altitude: 8,634 m (28,326 ft)
Average ground speed: 61.19 km/h (38.03 mph)

Each day (solar cycle), Solar Impulse 2 was flown on a trajectory that entailed: (1) using solar power during the day to run the engines, gain altitude, and charge the batteries, and then (2) using batteries to run the engines while gradually gliding down to lower altitudes at night.
