We're big fans of charming, ungainly Solar Impulse, and of Captain Bertrand Piccard and Andre Borschberg's quest to circumnavigate the globe in a solar-powered plane. In case you missed the live stream: the Swiss flier just got a little closer to that goal by completing its first international flight, taking off near Berne, Switzerland and landing in Brussels, Belgium, just under 13 hours later. That's half the flight time of an earlier test, in which the craft's 200-foot wingspan, covered with 12,000 photovoltaic solar cells, kept it aloft for 26 hours. Of course, a controlled test flight is one thing -- making solar-powered flight commercially viable means proving your plane can successfully navigate busy airspace. To see Solar Impulse come in for a smooth landing, peep the video after the break. Forbes Solar Impulse

We've been following Captain Piccard's Solar Impulse solar-powered airplane for a few years now. Today,  right now  as a matter of fact, the pioneering Swiss HB-SIA aircraft with 200-foot wingspan is attempting its first international flight. The flight to Brussels began at 8:40am (0640GMT) and should conclude about 12 to 13 hours later when Andre Borshberg brings all 12,000 photovoltaic cells to the ground in a controlled (we hope) landing. If successful then we can expect the craft to take on the Atlantic, Lindbergh style, in 2012 or 2013.

Scaled Composites is best known for creating  commercial spaceships  for Sir Richard Branson, but it turns out the firm can construct more conventional flying machines, too. The company has joined forces with Northrop Grumman to build the Firebird, a flexible new plane that's a veritable surveillance Swiss Army knife. Part  Predator  UAV and part traditional aircraft, the Firebird can take to the skies with or without a human at the controls as it combs the earth for enemies of the state. What's more, the airframe's HD video and infrared cameras, radar, and communications gear in the fuselage are able to gather info simultaneously to find the bad guys, and those payloads are easily swapped for other equipment through a universal interface. It's scheduled to strut its intelligence-gathering stuff during a military exercise in a couple weeks, and if all goes according to plan, it'll become another terrorist tracking tool in the U.S. arsenal.

Panasonic has been kicking around the idea of a tricked-out Android-based in-flight entertainment system for awhile, and now it's ready for airlines to start retrofitting their livery. The system, dubbed eX3, runs Android, relieving restless fliers with news, live television, games, and what the company calls on-board social networking, but that's mostly a nod to the Facebook app. Other amenities include broadband internet access and GSM service, touchscreen controllers, capacative screens, proximity sensors, and, in some cases, 3D displays. Not going to front -- we're stoked on the idea of tuning out on-board babies via multi-hour Angry Birds sessions, but we're seriously hoping the airlines ignore one of the system's marquee features: in-flight video conferencing.
