Found this very interesting UFO video today. Took place on a flight on January 30, 2010 on a flight from Manchester, England to Bulgaria. Photographer's daughter spotted it and then pointed it out to her father.
You can read more details from the YouTube site itself, just click on the video to watch it.
UPDATE: February 20, 2010-Seeing the above video made me think of something that I wrote about a long time ago. Finally found the link to it and you can check it out. Its a plan to "float" up to space instead of "blasting-off" to space. Check it out (http://aerospacedreams.blogspot.com/2008/10/new-means-of-getting-to-space.html)
