Grey magic was talking about the solar ones that stay up forever, I was responding to that with your link, which states that the longest one of those
aircraft have been been up continuously is 54 hours.
Those solar aircraft are VERY weak...not I'm not saying it needs inch think steel that encompasses it...what I'm referring to is the one that in
2003 simply disintegrated mid flight on a beautiful day in Hawaii...no weapons fire, no thunderstorm, simple nominal flight destroyed it.
