Most parents love taking their kids into work with them, once in a while. One father in New York did just that and got in hot water. Air traffic controller Glenn Duffy not only took his two children into work, he let them have a go at his job. JFK airport is one of the largest airports in the world, handling a thousand takeoffs and landings a day. But at approximately 8 pm on the evening of Feb. 16, 2010 a child was caught on tape in the control tower directing air traffic and giving instructions to pilots. Glenn Duffy brought his son into the control tower  allowing allowing him to direct air traffic and also let his daughter do the same thing the following day.

The TV networks broadcasted recordings of the boy clearing airliners to take off, and directing pilots to change communication frequencies. Preliminary reviews of the incidents, which occurred on February 16 and 17, found that the controller had allowed his son to communicate at least five times with various pilots after 5pm the first day, and allowed his daughter to talk to pilots twice after 4:15pm the next day.

The airplanes they were directing had 200 passengers on board.

At times the pilots seemed amused rather than worried upon hearing the young voice. One pilot told the boy, who is believed to be 8 or 9 years old, that he did an "awesome job" and another called him "amigo."

The Federal Aviation Administration  (FAA) didn’t treat this event as a joke. It investigated the controller, as well as a supervising controller. Both were relieved of their duties, the FAA said.

"This behavior is not acceptable and does not demonstrate the kind of professionalism expected from FAA employees," the agency said in a statement.

The Federal Aviation Administration (FAA) said an air traffic controller in Knoxville, Tennessee, went to sleep on the job during a midnight shift on Feb. 19, 2011. The sleeping controller didn't simply nod off -- he made a bed on the floor of the control tower, using couch pillows from the employee break room and a blanket.

The second controller in the tower, working on a different floor, got calls from pilots who had heard only radio silence. Alarmed by the silence, several times he entered the room where the sleeper was the sole controller on the overnight shift and shook him awake. Each time the controller was awakened, he promised he would stay alert and resume his duties. But he would return to his makeshift bed and resume sleeping when the colleague left, the official said. The second controller who was awake handled seven flights alone, including a Delta Connection arriving from LaGuardia and at least four "Lifeguard" flights. "Lifeguard" flights are planes with an urgent medical mission. The snoozing controller responded to one radio call but sounded groggy. The recording was unintelligible.

The revelation of this incident comes on the heels of another sleeping controller the previous month at Washington, D.C.'s Reagan National Airport. A controller there on his fourth consecutive overnight shift left the radio tower silent after apparently nodding off. Two commercial airliners were forced to land on their own.

One veteran air traffic controller contacted by ABC News said the incident at Reagan would not have presented a danger to passengers, because pilots are trained to land without air traffic control, but that it was highly unusual.
