The FBI and Federal Aviation Administration is investigating an incident, which occurred over Houston, Texas at about 10:30am on Monday morning.

Continental Airlines flight 1544 to Cleveland was flying at 5,000 feet just east of Bush Intercontinental when the pilot radioed the control tower to report an unidentified object trailing smoke heading in his airspace.

There was no collision and the officials say the 148 passengers on board the Boeing 737 were in no immediate danger with the flight continuing on to it’s scheduled destination.

The FBI’s Joint Terrorism Task Force is involved in the investigation and both the FBI and the FAA believe what shot past the cockpit window was a high-powered model rocket, although they have not confirmed that this is what happened.

FBI spokeswoman Shauna Dunlap stressed that it is not yet certain that the object was a rocket.

"We don’t know if it was a rocket or what. We will interview everyone and determine the validity of what was seen."

The plane arrived in Cleveland, Ohio at 2:13pm and according to 11 News who broke the story, was met by Continental and FAA officials, who interviewed the passengers on board and the crew.

Anyone wishing to fly model planes or rockets in controlled airspace must notify and gain permission from the FAA. The FAA confirmed that there were no requests to launch or notifications filed for the Houston area for Monday and added that there are no official launch sites within 50 miles of Houston.
