Aviation Analyst: To combat human error involved in air traffic control, Miro Jets Inc  has recently installed each of its DC-10 passenger planes with a special anti-collision device  The device alerts the DC-10, via a red light, when another plane is slightly more than three minutes away from a potential collision  The red light comes on and stays on until the approaching plane is safely out of range  Aviation experts at Miro Jet Inc  have determined that three minutes is ample time for a plane to divert its respective flight path to avoid a collision
Ttherefore, if the red light on the anti-collision device is off, the DC-10 is more than three minutes flying time from any plane
Recently, a near collision in which both planes were less than 90 seconds flying distance from each other was averted only by the prompt actions of air traffic controllers.
