A pilot has told how his passenger jet came with feet of being hit by a UFO while flying at 34,000 feet over the Berkshire countryside.
The captain was so convinced that the "rugby ball" shaped object would smash into the Airbus that he ducked as it headed towards the cockpit.
The pilot reported the incident to air traffic control and checked the aircraft's instruments immediately after it shot past, but there was no sign of the mystery object.
It appeared so suddenly out of a left hand side cockpit window, that the aircrew had no time to take evasive action, before it passed within a few feet of the jet, The Telegraph reports.
An investigation by the aviation authority has been unable to establish an earthly explanation for the UFO, which was described by the captain as bright silver with a metallic construction and "cigar/rugby ball like" in shape.
