I thought a plane had to be flying close to the speed of sound, to gather clouds around it. Guess not. Because Predator drones only get up to 135 miles per hour. And this one appears to be changing the temperature and pressure of the surrounding air -- allowing clouds to form. Strange.
The picture is from this Air Force presentation, which the kind and thoughtful Stephen Trimble pointed us towards.
UPDATE: Our commenters say it's a likely fake. And I think they're right, as usual.
