Blimp crashes at US Open
Spectators take to social media
Spectators at the U.S. Open say a blimp crashed at the PGA Tour event in Wisconsin.
Several people on social media say the blimp appeared to have caught on fire.
Instagram videos show someone parachuting to the ground.
Justin Maynard is a sales manager for AirSign, the advertising company that operates the blimp.
Maynard says only the pilot was on board the craft. He says the company's operations team on the ground confirmed citizen video on social media showing the blimp going down.
Maynard says he is "not 100 percent" on the condition of the pilot but that believes he is alive.
