A helicopter that was supposed to deliver supplies to the Jeep Jamboree along the Rubicon Trail crashed Friday.
Two people were sent to the hospital for injuries from the crash, while two others on board were able to walk away.
Both the NTSB and the FAA are investigating the crash.
The Jeep Jamboree office in Georgetown was closed Friday, but neighboring businesses say the annual event always helped boost sales.
In years past, locals say Jeep Jamboree organizers have used a helicopter to bring in supplies and event, at one point, a piano.
According to Heli-Flite, the company that owns and operated the downed aircraft, Jamboree organizers hired the helicopter to bring in supplies and three of its own people. The pilot, employed by Heli-Flite, and one Jamboree member were taken to the hospital with non-life-threatening injuries.
It’s unknown what led to the crash.
