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
