The story so far:
09 March 2015 — left Abu Dhabi on the first solar-powered round-the-world flight
http://hhg2tech.blogspot.com.au/2015/03/solar-powered-round-world-flight.html
21 April 2015 — a series of relatively short flights lead to a landing in Nanjing, China
30 May 2015 — after waiting in Nanjing for suitable weather, took off for Hawaii — expected flight time, at least 120 hours (5 days & nights), non-stop. A change in the weather forced a landing in Nagoya, Japan
28 June 2015, 18:03 UTC — Solar Impulse 2 took off from Nagoya. Next stop Hawaii.
29 June 2015, 03:17 UTC — passed the point of no return
