UFO Appears On Screen During British News Interview [Video]

During an interview with Parliament member Tom Watson on England's Channel 4 news, a mysterious object is seen zipping across the background from right to left. The object appears to be traveling at a high rate of speed and with a downward trajectory which makes it difficult to explain it being an airplane or a bird. Could it be an alien spaceship? Great Britain has big problems right now and an alien craft is probably the last thing they need right now. Judge for yourself.
