Construction began on the one-story hangar last year; a permit for the foundation was issued in October, according to the Idaho Statesman, which enlisted the insight of multiple engineering experts to explore potential causes of the collapse. Some speculated that high winds could have contributed.
Winds gusted as high as 17 mph on the day of the collapse, and the Statesman said there was a 20-mph gust about 10 minutes before emergency services were called to the site. OSHA recommends assessing if lift operations should be suspended when winds reach that 20 mph threshold.
