Talk:Solar-powered plane completes 26-hour flight

Information could be more extended
Incomplete information: pilot's age, airplane's wing span (it seems quite extended in the movie (external link), kind of electrochemical batteries to store energy. Was the temperature drop in the cockpit a technical breakdown or just due to the lack of a heating system to save energy and poor isolation to reduce weight? The maximum speed reached, 68 knots has been omitted.

On the other hand, the speed should have been given in meters per second or kilometers per hour, more widely used units, even the organization gave the average speed in knots rather than in miles per hour. No mention to the airplane's next challenge, flying around the world in 5 stages in 5.20.2013. Why in stages? It has not been commented that these flights are programmed around the Summer solstice, when there are more sun hours and flux of light radiation is higher above the tropical latitudes. It means that only has been proven effective during the Summer months. Finally, a 24-26-hour flight doesn't prove yet indefinite flight since the plane has been probably storing energy to take off. We don't know whether the energy stored was the same or higher 24 hours later. A 4 to 5-day flight would have been more convincing.

Finally, there's a statement that could be misleading: "in theory, the plane could fly indefinitely, given that there is enough sunlight to power it." Sunlight level at an altitude of 30 thousand feet can only be caused by day and night ratio and the sunlight angle of incidence. the weather has nothing to do since the kind of clouds at that altitude can hardly attenuate sunlight radiation. --Heathmoor (talk) 22:03, 9 July 2010 (UTC)
