MOUNTAIN GROVE, Mo. (KY3) - It happened again. Another loud sonic boom hit the Ozarks.

The Mountain Grove Fire Department reported a sonic boom from the region Sunday morning. A photo from the department shows the path resulting from the sonic boom. Viewers have called the KY3 newsroom, saying it briefly rattled their homes in Texas and Wright counties.

In a Facebook post, the Mountain Grove Fire Department shared this explanation on the sonic boom:

“Sonic boom is an impulsive noise similar to thunder. It is caused by an object moving faster than sound -- about 750 mph. An aircraft traveling through the atmosphere continuously produces air-pressure waves.

Any military jets are very capable of hitting these speeds. The military has acknowledged the testing of a new jet called the F-15EX Strike Eagle released in April of 2021. There is a very good chance this what caused our sonic boom today.

The fastest commercial airliner is the 747-8. It hits top speed of 659 mph. Almost 100 mph too slow to hit the needed 750 mph for breaking the speed of sound.”

At times, a sonic boom can be heard from hundreds of miles away. Boeing told KY3 earlier this month the booms are generally a result of test flights, which have become normal in the Ozarks.

″It was quite loud. It really shook our windows,” said Lt. David Todd with Mountain Grove Fire Protection District. ”The unique thing about this sonic boom is it actually occurred over the city of Mountain Grove.”

With multiple sonic booms reported in September, Todd says these occurrences may be more common than you think.

“They used to happen a lot in the 90′s, but they have slowed down,” said Todd. “I think we’ve only heard maybe two or three this whole entire summer.”
