Federal investigators were working Thursday to try to determine what caused a steel airplane hangar that was under construction in Idaho to collapse the previous evening, killing three people and leaving several others badly injured.
The Boise Fire Department said in the morning that the scene was turned over to OSHA investigators. Though the hangar is at the Boise Airport, it is privately owned by Jackson Jet Center, a charter flight and maintenance company.
The Ada County Coroner’s office was expected to release the names of those killed once family members had been notified.
Nine other people were hurt, including five who had critical injuries and were taken to area hospitals. Officials with Saint Alphonsus Regional Medical Center said they were not able to issue an update on the condition of the injured patients because of privacy laws.
The collapse was reported about 5 p.m., and first responders had to stabilize the massive structure while trying to rescue those who were trapped inside and underneath it. Steel girders and panels were bent, and a large crane was folded in the wreckage.
