Military officials in Vietnam have seized three mysterious metal balls after they reportedly fell from space and crash-landed in the north of the country.
Witnesses saw the three balls, ranging from a half pound to about 100 lbs., flying around before they crashed early Saturday morning, CBC News reports. The smallest landed on the roof of a house, while the largest landed away from residences in a maize field.
Investigators have determined the objects are Russian-made, although they could have been sold to other countries for use. The objects were identified as specialized compressed air tanks potentially from a rocket. They don't contain radioactive or explosive material.
The metal balls are still intact. A professor from Vietnam's State Space Science and Technology Program told local media source VietnamNet Bridge this could mean they fell from less than about 60 miles, and might be the result of a failed satellite launch.
