LaGuardia Airport Clip - Passengers aboard a Southwest Airlines flight at New York's LaGuardia Airport on Tuesday morning, were all set to leave for Denver, when their plane clashed with an American Airlines plane and sustained some damage to its left wing, forcing the plane to be grounded.

Airport authorities say the Boeing 737 Southwest Airlines flight 449 was just set to depart from LaGuardia when the accident occurred. Reports indicate that there were about 148 people aboard the plane - including 5 crew members.

The American Airlines plane involved in the LaGuardia Airport 'clip' incident had reportedly arrived from Dallas and was being moved to a gate when the crash occurred. The American Airlines flight 1104, which had just one more person aboard than the American Airlines plane, also sustained some damage to its tail wing.

But no one was injured in the accident. Passengers aboard the planes took to social media to express their surprise at the bizarre accident and also posted pictures of the damaged planes.

The cause of the LaGuardia Airport 'clip' is still unknown. Reports indicate that it was drizzling at the time of the accident. However, it is unknown if the weather had a direct impact in the clash. The Federal Aviation Administration is reported to have opened an investigation into the incident.

Reports indicate that the damaged planes did not need to be towed. Southwest and American have reportedly grounded the planes and are assessing the damage. The Southwest flight for Denver reportedly left LaGuardia more than twenty minutes late on Tuesday morning.

Some critics have blamed the accident on LaGuardia Airport traffic controllers.

LaGuardia, which was built in the 1930s, is one of the oldest and busiest airports in the country. Despite the growing traffic handled by the airport, critics say it is run with outdated facilities.
