Rocket Launcher Tube Found at a Home Near N.J.'s Newark Liberty International Airport

Federal investigators are examining what appears to be an inoperative military rocket launcher tube found Friday morning on the front lawn of a Jersey City home that sits directly in the flight path of busy Newark Liberty International Airport.

Jersey City Police removed the tube, and the incident is now being investigated by the Joint Terrorism Task Force and the Federal Bureau of Investigation.

The New York office of the Bureau of Alcohol, Tobacco and Firearms told FOX News that it appeared to be a military firing tube, and that there was no evidence of any explosive device discovered at the scene.

The Associated Press reported that the tube was an inoperable military training device, and that it was given to Army officials at Fort Monmouth.

Police said the device was believed to be about 20 years old, and that it posed no hazard. It may have been used for anti-tank training, police told the AP.
