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. Aviation experts at Miro Jet Inc. have determined that three minutes is ample time for a plane to divert its respective flight paths to avoid a collision. Therefore, if the red light on the anti-collision device is off, the DC-10 is more than three minutes flying time from any plane.
Which of the following, if true, most fundamentally calls into question the aviation analyst's argument?
(A) 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.
(B) Some aviation experts warn that in certain cases three minutes may not provide sufficient time for aircrafts to maneuver without causing onboard injuries.
(C) The anti-collision device only signals planes of oncoming directions, not those planes that are flying in parallel.
(D) When two DC-10's approach each other the red lights on each aircraft do not necessarily turn on simultaneously.
(E) The DC-10 is not the only aircraft model to have been installed with the anti-collision device.
