An airport in Houston temporarily grounded all flights on Tuesday after two private jets collided on its tarmac, officials said.

The incident took place around 3:30 p.m. CT when a twin-engine jet departed "without permission" from the William P. Hobby Airport runway and collided with another twin-engine jet that was landing on the runway, according to the Federal Aviation Administration.

No injuries were reported in the collision and it's unclear how many people were on board either aircraft, the FAA said.

The departing plane was identified as a Hawker H25B, a corporate aircraft model, while the arriving flight was a Cessna C510 business class jet, according to the FAA.

The two private jets "clipped their wings as they were moving on the airfield," Hobby Airport said in a post on X.

The airport remained under a ground stop while crews worked to remove the debris, the post said. The airport announced the debris had been cleared just after 7 p.m. and flight operations had been restored.

Hobby Airport is located 7 miles from downtown Houston.

The incident remains under investigation by the FAA and the National Transportation Safety Board.
