MADISON, Wis. (AP) — Foggy conditions may have contributed to the fatal crash of a University of Wisconsin Med Flight helicopter last year, according to documents released Thursday.
The National Transportation Safety Board said it has not yet found a probable cause of the May 10 crash that killed the pilot, a doctor and a nurse. But hundreds of pages of documents released by the board indicate that foggy conditions may have limited the pilot’s visibility.
Two other medical helicopter crews in the area told investigators they declined requests for flights that night because of the danger brought on by deteriorating weather, records show. One of them, a pilot for a La Crosse hospital’s program, said he noticed “fog and scud forming” on the bluffs near the Mississippi River during an earlier flight.
