Two planes were left to land without guidance Wednesday when they heard no response from the air traffic control tower.
The controller who was on duty is a 20-year veteran of the job, and has admitted he was asleep at the time of the incident. The FAA has suspended the controller while they investigate what happened.
Bob Richards is a former air traffic controller and author of "Secrets from the Tower". Richards talks to Ali Velshi about Wednesday's close call at Reagan National Airport.
