A couple of days ago, just as the latest weather front was approaching our area, my wife noticed an unusual cloud formation almost overhead. I quickly grabbed her little digital camera and took a picture.

This is the original image, including a flaw in the camera which appears when the zoom is set to higher than 1.5 ( I'm getting the camera looked after under warranty).
This is a negative image, after painting out the flaw, and rotating the original. To me, it looks like a number of jet fighter planes flying in formation. Maybe aliens?
