Mysterious Metal Orbs Discovered In Northern Vietnam

On January 2, 2014, several mysterious metal orbs were discovered in three provinces in northern Vietnam baffling residents and officials. Two unidentified metal orbs were discovered in the provinces of Tuyen Quang and Yen Bai in northern Vietnam, following a loud noise from a supposed aerial explosion.

The first sphere, about 50kg in weight, was found by residents in Tuyen Quang and has two sealed ends, with a perimeter of approximately two meters and foreign characters on its surface.

Locals claimed they could hear 'thunder' in the minutes before the items were recovered. 

One of the orbs, around 5.8kg in weight and 30 centimeters in radius, narrowly missed a house, landing in the garden of a house in the Yen Bai region, while the smallest, weighing only 250 grams, landed on a roof before rolling onto the ground.

Professor Nguyen Khoa Son of the State Space Science and Technology Program told Vietnam.net the objects could be part of a satellite fuel system.

He said the pieces could be the remains of a failed satellite launch or even parts of a decommissioned satellite which returned to earth.
