Free Flight is a new air traffic management concept that is being developed, and some believe that it could be implemented within the next decade.  If true Free Flight is implemented fully it would take the place of any form of central control including air traffic controllers.  Supporters might argue that it will be a more productive, fiscally sound, and safer system.  Can you continue to trust controllers and the risk of human error as they continue to be over worked, under trained, and under paid?  Can you continue to risk the chance that they will strike in the case of a labor dispute?  Opponents would argue that pilots don't have a perfect record either, and that their should be a third part to de-conflict flight paths, monitor air space, and control assents, descents, landings, and take-offs.  There is a very long list of reasons for and against free flight.  Additionally, there are several forms of free flight.  Do some research and tell everyone what you think.REFERENCES:  Must be APA  style.
