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.’
