A strange sight in the Texas night sky over the weekend had many people talking about fireballs and alien invasions. But, alas, the real culprit has been identified, a much more Earthly one.
Police in East Liberty County got a 911 emergency call at around 8:30 p.m. on Saturday from a person reporting "red fireballs in the sky." Responding police officers, along with a dozen locals, described seeing four orange lights moving slowly in a line high in the sky. Police scopes revealed that the objects looked like hot air balloons — complete with flames — but were much smaller and did not have the signature gondola at the bottom.
Even more mysteriously, the lights were estimated to only be a few thousand feet off the ground, and yet they moved silently. No known airplane or helicopter technology could fly that low and remain so quiet. Within minutes the UFOs were gone, having disappeared into the night. They didn't fly away but instead simply blinked out of existence; some eyewitnesses thought they had vanished behind a passing cloud and would reappear at any moment, but they never did.
