At least one person is believed to be dead after a small plane crashed at Aspen Airport in Colorado.
While emergency crews are still at the scene, US reports state that three were on board the plane at the time of crash.
One suffered minor injuries, while another is being treated for critical injuries and another lost their life, according to the local Pitkin County Sheriff's office.
"So sad! Horrible plane crash we just saw happen at the Aspen airport," Rimes wrote.
And Nealon opted for a more detailed account.
Horrible plane crash here at Aspen airport. Exploded into flames as it was landing. I think it was a private jet," he began.
"Airport is closed now. I think I'll drive back to LA after seeing that," he added.
"Fire trucks and other emergency vehicles still at scene. No word on survivors or who was on jet but I can't imagine there are survivors.
"Didn't look like there could be survivors but just hearing some survived but critical," he said on Twitter.
