A Virgin Atlantic Airbus A330-300 and an EgyptAir Boeing 777-300ER were both damaged after their wing-tips clipped at New York's John F Kennedy International airport.
A tweet from the Port Authority Police Department confirms that both aircraft returned to the terminal and that there were no injuries.
One image on social media show the wing-tip of the Virgin A330 completely shorn off, and being transported in the back of a pickup truck.
The outboard leading edge of the 777-300ER's right wing also suffered damage, with a large section missing.
Both aircraft were apparently taxiing to depart when the accident occurred.
Flight tracking websites indicate that the A330's registration is G-VRAY, while the Egyptair 777's is SU-GDL, but the airframe identities have yet to be confirmed.
Flight Fleets Analyzer shows that G-VRAY is managed by AerCap. It is powered by Rolls-Royce Trent 700 engines and was delivered in 2012. It also shows SU-GDL is managed by GECAS and was delivered in March 2010.
