London, May 29 : Aliens from outer space might not be a thing of science fiction anymore, especially after a small Vietnamese island was showered with metal-like debris, courtesy a UFO explosion.
According to reports, the unidentified flying object is not believed to be a plane as none have been reported missing in the area.
Investigators are working on the theory the explosion happened five miles above the ground.
A search of Phu Quoc island off southern Vietnam uncovered shards of grey "metal" up to four feet long.
On May 29, soldiers examined the area for clues as airlines in Vietnam, Cambodia and Thailand insisted none of their aircraft were missing in the area.
Villagers in the nearby Cambodian province of Kampot said on May 27 that they had heard a loud explosion.
A day later they found chunks of material near the coastline.
After the explosion Kung Mony, of Cambodia's Air Force, claimed it could have been a foreign plane but he later backed down from the theory. One explanation could be that the plane was a military one - but none of the nearby countries has admitted to losing any aircraft.
