There is still no official explanation for the loud boom heard across the Wichita area Saturday afternoon.
No evidence of an explosion was ever found and no damage was reported.
Several people reported seeing a flash in the sky before the boom, which is consistent with the sonic boom that sometimes accompanies meteors as they enter the atmosphere and burn up.
The American Meteor Society keep logs of fireball reports and 30 have come in so far from Saturday afternoon. Reports are clustered around Wichita and Oklahoma City, with people seeing a burning object in the sky and hearing the delayed boom. These reports all came in around 1:30 p.m. A couple reports indicate that whatever entered the atmosphere appeared to break into pieces toward the end of the event.
