After a tornado in 1967, St. Louis-area hospitals revised their diaster plans, according to a Throwback Thursday article on the Hospitals & Health Networks website.
Missouri Baptist Hospital and St. John's Mercy Hospital spent 10 years developing their own disaster programs.
But after a 1967 tornado, the facilities was realized that the police, firemen and civil defense workers were better equipped to take full charge of the drill.
The new drill transported patients by helicopters, ambulances and trucks to five hospitals.
