A United Airlines Airbus A319 taxies to a gate after landing at San Francisco International Airport.

SAN FRANCISCO −A mishap between two United Airlines planes at San Francisco International Airport forced passengers to deplane and fly in a different aircraft to their destinations, the airline confirmed on Wednesday, Aug. 3.

The incident took place on the evening of Monday, Sept. 1, when two United Airlines planes touched tails at the airport, the airline confirmed to USA TODAY.

According to the United, the collision − involving Flight 1871 traveling to Denver and Flight 796 bound for Boston − took place as one of the aircraft pushing back from the gate "made contact with the tail of a parked United aircraft."

The incident took place around 9:10 p.m. local time, Federal Aviation Administration spokesperson Steve Kulm told USA TODAY.

"This occurred in an area where air traffic controllers do not communicate with flights," Kulm said in an email.

According to Kulm, United Airlines Flight 1871 was towed back to the gate where passengers "deplaned normally."

No passengers or crew members were hurt, United said, noting the airline "arranged for different aircraft to take our customers to their destinations."

TV station ABC-7 in San Francisco reported the collision caused damage to at least one aircraft's wing.

The cause of the crash was not immediately known, and neither the airline nor the FAA responded when questioned about the reported wing damage.

The FAA said the agency continues to investigate the crash.
