Officials from the Federal Aviation Administration and National Transportation Safety Board arrived in Honolulu Thursday to investigate a near mid-air collision involving two commercial jetliners. The incident happened on April 25th when an eastbound United Airlines Boeing 757 had to avoid a westbound U-S Airways Boeing 757 about 200 miles northeast of Kona. The planes only had about eight miles laterally when the United crew responded to an alert with an avoidance maneuver. The planes came within 5.3 miles laterally and 800 feet vertically of each other.
