Federal officials are investigating how two passenger jetliners got on potentially dangerous paths toward each other near Hawaii at an altitude of about 33,000 feet.
On April 25, an eastbound United Airlines flight received an alert from its onboard Traffic Alert and Collision Avoidance System about a westbound US Airways flight, the Federal Aviation Administration said in a statement Friday. The planes were about 200 miles northeast of Kona.
In that airspace, planes must be separated by 5 miles laterally or 1,000 feet vertically, according to the FAA.
