Bush Intercontinental Airport was on high alert Tuesday afternoon after ground employees feared a piece of luggage exploded shortly after the plane landed.
Airline workers were unloading baggage and a bag hit the ground causing a loud popping noise, MyFoxHouston.com reported.
It was first thought to be an explosion, but was quickly deemed a "non-event" by an airport spokeswoman.
No injured were reported.
Information about the plane was not immediately available.
