Sky in Texas continues to fall on Us.

DALLAS — A six-pound chunk of charred metal blasted through the roof of a house in Southeast Oak Cliff Tuesday evening.
The object crashed through the second floor of the home in the 7800 block of Buford Drive before coming to rest in the kitchen on the ground floor.
No one was home at the time of the incident and there were no injuries.
The Dallas Fire-Rescue biohazard unit checked the unidentified flying object for radiation and found none. Police say they have no idea what the metal is or where it came from. State and regional officials have been notified.

Investigators say they are not aware of any other reports of similar activity in the area.
Two large man-made satellites collided in orbit over Siberia on February 10, and military officials have been on alert since then for possible falling debris.

The 6-pound chunk of metal crashed through a roof sometime Tuesday in southeast Dallas, and a day later, officials were perplexed about its origin.
The incident happened in the 7800 block of Buford Drive, which is northeast of the intersection of Interstate 35E and Interstate 20.
No one was home when it hit, and police were summoned at 5:19 p.m., said Sr. Cpl. Kevin Janse, Dallas police spokesman.
The debris was described as a 6-pound piece of metal with two drill holes in it, Janse said.
He said the chunk hit "with enough velocity to break through the [homeowner's] roof and second floor."
Officers were unable to determine the source of the fallen debris, but a biohazard unit from Dallas Fire-Rescue determined that it tested negative for "radiological activity," Janse said.
Several state agencies have been notified, Janse said, including the Texas Department of Public Safety and the Texas Commission on Environmental Quality.

"No other reports of similar activity have been reported at this time in the DFW Metroplex," Janse said.

On Feb. 15, a fiery object the size of a pickup truck was observed streaking across the sky from the Texas Hill County all the way to North Texas. Astronomers and federal aviation officials agreed a few days later that it was a meteor that probably disintegrated before it hit the surface.

Earlier, however, aviation officials had speculated that the flaming object might be "space junk" flung from the collision of two satellites over Siberia. That collision sent thousands of pieces of debris into the Earth's orbit, pieces that experts said could remain for thousands of years. Astronomers said that trajectories of that debris field did not lead to North Texas.
