The Federal Aviation Authority is investigating claims of a near collision between two passenger planes over Hawaii last month.
Apparently, on April 25th, a United Airlines flight dropped 600 feet in order to avoid an oncoming U.S. Airways flight. At just two miles apart, the planes could have collided within twelve seconds due to their speeds.
The incident went under the radar until this week, when passenger Kevin Townsend published an essay on the subject. Now, the FAA and both airlines are cooperating to investigate the close call.
