Solar Craft Flies Through Two Nights

An anonymous reader writes "A solar-powered, unmanned craft has flown for 54 hours — a record for both unmanned aerial vehicles and solar craft. None before has managed to store enough solar energy to fly through more than one night. There is also a video showing the 18m carbon fiber wing craft being launched."

Actually, according to Wikipedia, the equatorial circumference of the earth is 40,075.02 km. So the plane would have to be traveling at 1669.7925 km/hr to keep pace with the sun.

What? Imperial units you want? Fine. 1 kilometer = 0.621371192 mi according to Google, so the plane would have to travel at 1037.56095611766 miles per hour. So the other poster who said 1000 was actually quite close.

What the hell kind of moderation is that? It's a silly typo, it's already been commented on, and the complaint about hte typo adds nothing to the discussion.

You found something to nitpick and a few peeps had moderation points burning a hole in their pockets. Whoop-de-fucking-doo. Let's just pause the discussion so everybody can golf-clap.
