Mike, Well, they certainly didn't choose a full moon night to fly it. Actually the moon puts out virtually zip energy compared to the sun. The key in this demonstration was that the aircraft engines use less energy during the daytime portion of the flight than the solar panels were taking in and then store the excess in the lithium-ion batteries for use in the night portion of the flight. What I wonder is if this aircraft showed up on radar, and if it did, did they stuff a portion of the plane with aluminum foil so that they could track it? My assumption is that the carbon fiber would itself NOT reflect radar. On the other hand, I believe the battery cells would have been made out of metal so maybe that gave them the radar signature they needed for safety reasons. craig
