Video on social media shows the wing of a United Airlines aircraft on fire before more than 100 passengers were evacuated ahead of a flight from Houston.

The United Airlines flight incident comes just days after two deadly plane crashes. Last week, an American Airlines flight traveling to Washington, D.C., collided with a U.S. military helicopter over the Potomac River. Sixty-seven people were killed, making it the deadliest incident for U.S. aviation in nearly a quarter of a century.
