Interesting footage of UFO being chased down by UK RAF Fighter Jets

On 10 April 2010, two fighter jets chasing what appears to be a UFO.

The 30-second clip, thought to be shot from a West Midlands service station park, reveals the saucer-shaped craft zipping over the M5, with the two jets in its wake.
​Former Ministry of Defence UFO expert Nick Pope told The Sun: “This is one of the best videos I’ve seen.”

He also said “It could be a new drone – that might explain the military jets, but you don’t normally test-fly secret projects in daylight. Alternatively, this could be the real thing – a UFO in our airspace and military aircraft scrambled to intercept, probably due to it being tracked on radar.”
