Two United Airlines planes taxing for takeoff "made contact" with each other on the tarmac at Houston's George Bush Intercontinental Airport on Nov. 18, according to the carrier. The collision caused a delay for both flights as passengers were forced to deplane and board new aircraft.

"United flight 544 was preparing to taxi when it made contact with the wing of United flight 2451, which had stopped after just pushing back from the gate," United Airlines told USA TODAY in an email statement. There were no injuries reported.

United flight 544 was scheduled to depart for Cleveland-Hopkins International Airport at 6:21 p.m., with United flight 2451 to head toward Orlando International Airport at 6:21 p.m., according to FlightAware.

Both aircraft returned to their respective gates, where all passengers deplaned, according to United. New aircraft were arranged to resume the flights, and both flights landed at their final destination following a delay of over two hours.

In September, two other United planes at San Francisco International Airport had a brief encounter when one was pushing back from the gate and "made contact with the tail of a parked United aircraft," the airline previously told USA TODAY.
