In 1958, a significant aviation disaster occurred in the United States when Capital Airlines Flight crashed near Tri-City Airport, Michigan. On April 6, amid severe weather including heavy snow and low visibility, the Viscount turboprop aircraft went down. Tragically, all 47 onboard perished, marking it as among the deadliest U.S. commercial aviation accidents of its time. This incident highlighted the challenges of aviation safety in adverse weather and prompted increased scrutiny on safety protocols.
