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.
The USGA released a statement about the crash:
"According to local authorities, a commercial blimp not affiliated with the USGA or the U.S. Open Championship broadcast crashed in an open field approximately a half mile from the Erin Hills golf course at approximately 11:15 a.m. First responders were quick to arrive at the scene and the pilot is currently being treated for unknown injuries. No other people were involved in the incident and local law enforcement is currently investigating. Our thoughts and prayers are with the pilot at this time."
