Two Boeing 737 jets got a little too close for comfort Tuesday morning at LaGuardia Airport, the wingtip of one airplane clipping the tail of the other on a taxiway, the Federal Aviation Administration said.

No passengers were injured in the incident, the FAA said.

The FAA said that just before 11 a.m. the wingtip of Southwest Airlines Flight 449, an aircraft preparing to depart LaGuardia for Denver, "made contact" with the tail of American Airlines Flight 1104, a flight from Dallas that was in the process of taxiing to its gate.

The Associated Press said the left winglet -- a vertical fin at the tip of a wing designed to improve airflow and fuel efficiency -- was ripped off the Southwest plane, though the FAA did not immediately confirm the report.

The FAA said it would investigate the incident, but did not provide any additional details.
