What evidence do you have that it was done with aliens?

Not saying that they're ALIENS, but then again, what else could fly like that and create a crop circle formation at the same time? We don't know what they ARE, but we DO know that they AREN'T Doug and Dave or their silly friends at CircleMakers.com.

The Wicked Witch of the West? The films of her flying are fairly high-resolution and in glorious Technicolor.
