SPRINGTOWN (CBSDFW.COM) – Police in Springtown reported a “large boom” near the Salt Creek area on Wednesday morning, but were unable to identify what made the noise. In a post on Twitter, the Springtown Police Department added that there were no signs of an explosion or fire nearby.

Lockheed Martin released a statement saying:

We did have flight operations in that region today that included supersonic testing. Our pilots work to perform these flights in a manner that hopefully impacts the fewest number of people while still allowing us to make sure each aircraft made meets our customer requirements.  Atmospheric conditions sometime make a difference in whether the sonic booms reach the ground.  It is our intent to disturb the community as infrequently as possible. 

The Azle Police Department also reported the sound, saying that authorities had received numerous phone calls asking about the loud boom. Officials said that it was heard “over a wide area.” Some homes and businesses in Azle even experienced some shaking. No damage was reported.

The U.S. Geological Survey had not posted any information about an earthquake in North Texas, authorities in Azle continued in a post on Facebook. The most recent temblor had been on Wednesday morning in central Oklahoma, although the Azle area has seen numerous quakes in the past.

A short time later, officials in Parker County were able to explain the sound. They reported that it was an F-16 flying through the area. The noise was actually a sonic boom.
