ROY — Two men were critically injured Sunday afternoon in a small plane crash in Weber County, officials said.
The crash occurred off southbound I-15 in Roy after the plane hit a billboard, the Utah Highway Patrol said.
The National Transportation Security Administration said the plane crashed about a half-mile southwest of Ogden-Hinckley Airport soon after it departed.
One person was flown to a hospital and two people were transported via ambulance.
A video taken after the crash shows bystanders parked off the freeway and a crowd of people surrounding the smoking plane to apparently help.









One person who stopped to help suffered smoke inhalation and was taken to a hospital for treatment, said Roy police officer Stuart Hackworth.
Hackworth said officers were grateful for those who stopped to help immediately after the crash, but asked that bystanders to clear the area while first responders were working on scene.
No other injuries were reported.
Southbound I-15 was closed in the area of the crash. The UHP asked people traveling I-15 north to drive cautiously and not slow down to observe the crash.
The Federal Aviation Administration and National Transportation Security Administration will investigate.
