Ken DeFoor, Liberty County Sheriff's Department chief deputy, told The Houston Chronicle Tuesday an ExpressJet Airlines pilot claimed to have seen on object flying near Houston's George Bush Intercontinental Airport.
"The FAA is in the process of debriefing the pilot today (Tuesday)," DeFoor said. "We are going to try and come up with a more definite track of this object and its path. We are trying to find out where it came from, where it went, and who may be responsible for it."
"No people were injured and no evasive action on part of the airplane was taken," DeFoor added regarding the Continental Express jet the pilot was operating at the time of last Friday's sighting.
The pilot, whose identity was not reported, said the object appeared to possibly be a missile or rocket.
DeFoor told the Chronicle authorities were investigating the possibility the unknown object may have been launched from the ground.
