The Federal Aviation Administration is investigating a near-miss by two airplanes over New York City last week.
A Delta Airlines Boeing 747 arriving at JFK came close to a Shuttle America Embraer E170 departing from LaGuardia Airport around 3:45 p.m. on June 13, the FAA said in a statement.
The aircraft were "turning away from each other at the point where they lost the required separation," the FAA said. Both planes landed safely.
The 747 was cleared for landing at JFK, but the pilot decided not to land and to circle around and try again, according to news reports. At the same time, the smaller commuter plane was taking off from LaGuardia.
CBS News reports that the aircraft were separated by four tenths of a mile horizontally and just 200 feet vertically at their closest point.
