Did you hear a boom Monday? It could possibly be...

SHREVEPORT, LA (KSLA) – An enormous "boom" heard across parts of Louisiana on Monday remains a mystery. Lots of people are still wondering what caused the earth to shake.
The majority of parish leaders are saying it was more than likely a sonic boom heard across 6 parishes in north central Louisiana.
Science professor Don Wheeler says a sonic boom is a possibility and could be heard over such a large area.
He also is not ruling out a meteorite.
"Did we have an explosion? Yes," says Don Wheeler, Delta Community College Science Professor.
"Where was it? Don't think it was at ground level, based upon seismic data. So, probably something that was airborne; possibly a military jet or the meteor possibility, as it was entering the atmosphere coming from northwest to southeast."
An earthquake has been ruled out, since there was no seismic activity.

A loud sound similar to an explosion that rattled windows in the region late Monday afternoon was most likely a sonic boom caused by high-speed aircraft or a meteor coming through the atmosphere, a pair of local experts said.
The apparent sonic boom happened just before 5 p.m. and affected the area southwest of Shreveport to around Vidalia.
“Looking at the path of the reports, there’s a definite linear path,” said Don Wheeler, a meteorologist at Louisiana Delta Community College.
Wheeler said there was no irregular seismic activity in the area during the period immediately before and after the apparent sonic boom.
“If indeed there was a meteor, they can come in at supersonic speeds,” Wheeler said.
There have been no reports of area residents seeing a meteor, but seeing a meteor was unlikely because overcast and daytime conditions, Wheeler said.
John Anderson, an assistant professor of physics at the University of Louisiana at Monroe, said the more likely culprit behind the sonic boom is a jet or high-speed airplane.
Anderson said the aircraft could have moved over the affected area in about 90 seconds if it was travelling at 750 miles per hour or faster.
“If it was an airplane, somebody’s in trouble,” he said.
Some residents reported seeing two planes.
A spokesman for the Federal Aviation Administration did not return a call and an e-mail seeking comment.
“There’s a lot of questions and few answers,” Wheeler said.
The APE program involves designing, fabricating and installing equipment used to maintain or demilitarize conventional munitions. Currently, the depot is working with Louisiana-based Safety Management Systems to do explosives testing for the Department of Transportation, and with Minneapolis-based Alliant Techsystems to install an explosives incinerator in Australia. Other projects have included deactivation furnaces, mobile brass certification units and priming and depriming machines.
