UPDATE (8:30pm) According to Broadwater County Sheriff Wynn Meehan, two men were "seriously injured" in the incident.
Meehan says the plane left Bozeman at around 3:30pm; power was lost in the Townsend area around 4:30pm. Though the men had obvious injuries, they were able to hold a conversation with first responders and were air lifted to two separate hospitals.
Meehan says it is still unclear at this time why the plane was flying low enough to have hit a power line, but the Federal Aviation Administration will be investigating.
