Two friends traveling together on an airplane headed to Seattle, Washington were lucky enough to spot a UFO - specifically a thin dark object zooming by - while gazing out the window, and get a photo (MUFON case 81157):
We were flying to Seattle when my bud saw his black thing appear in the sky. I was able to snap the picture right before it disappeared about 10 seconds later
Could this have been a bird or just some miscellaneous debris? Or was ET doing a flyby? What do you think?
