Image of the Day: Awesome pic of Solar Impulse plane in silhouette

In its series of photos of subjects in silhouette, The Big Picture included this spectacular image of the Solar Impulse plane during its successful 26-hour test flight last month.

Shot by Fabrice Coffrini over a Swiss airbase on July 8, the photo perfectly represents the promise and beauty of using solar power for flight. Try not to think too hard about Icarus as you gape at the enlarged version in the gallery below.
