"Testing my new Canon 60D camera filming out of the window after a few weeks of running through the footage for other purposes I noticed what I thought was maybe light reflecting from the windows on board however looking closer I can see there looks to be more to it.

What's strange is the way the object / UFO? appears to accelerate as it enters the frame from the left hand side. It couldn't be passing debris or another plane as it is traveling in a forward direction faster then anything I know of or have seen before and I am an aviation enthusiast."
