Hazards are created by failure to use radios to report positions and intentions when operating within the airspace, which can lead to collisions between aircraft unaware of each other. In 1996, an incoming United Express Flight 5925 collided with a King Air aircraft, which failed to report its intent to take off on a common traffic advisory frequency at non-towered Quincy Airport in Illinois. Some pilots fail to use the correct runway at non-towered airports.
