An unattended rental truck loaded with guns and pyrotechnics for the cable TV show "Sons of Guns" caused some tense moments at Dallas/Fort Worth International Airport Sunday afternoon.

Part of DFW's Terminal B was closed for two hours Sunday as airport security and the FBI located and questioned the driver of the rental truck left unattended outside the terminal, according to an airport spokesman.

An FBI spokesman says agents sent to the scene learned quickly that the truck was driven by a member of the crew of the Discovery Channel show "Sons of Guns." He says airport police called the FBI when the man told them he had guns in the truck.

The FBI says guns were found, but it was clear that the man was waiting for another member of the show's crew so they could drive to El Paso and Albuquerque, New Mexico to film the show.

An executive of the company that produces Sons of Guns says he regrets the incident, and he blamed it on "a colossal error in judgement by a member of our staff."

The incident happened near the location where volunteers greet the daily arrival of U.S. troops from the Middle East as they come home for rest and recuperation. Apparently the driver was oblivious to the heightened security on the anniversary of 9/11.

The airport spokesman says "You can only describe it as being unaware. Apparently there are people unaware of what our nation is going through."

Yes there are people like that. People who are completely clueless and ignorant of what's going on in the world around them. They don't read newspapers, or watch TV news, or listen to news on the radio. If they have Internet access, they spend all their time on Facebook and playing games.

They also don't read radio station websites like this, so that truck driver probably isn't  even aware that people are talking about him and the trouble he caused.
