A mystery cameraman has filmed two British fighter jets pursuing what looked like a UFO, according to media reports.
The dramatic 30-second video clip, which is believed to have been taken from a West Midlands service station car park in Britain, had drawn millions of hits on the Internet.
"This is one of the best videos I've seen. It could be a new drone - that might explain the military jets," the Sun quoted expert Nick Pope, who probed UFO sightings for the Ministry of Defence.
"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," he added.
The British defence ministry refused to comment on the alleged sighting, but confirmed it would scramble jets to meet an air threat.
A police official from West Midlands, however, said: "We are not aware of any reports of unidentified aircraft."
