Twenty years ago today, Galaxy Airlines Flight #203 crashed on take-off from Reno, NV on its return flight to Minneapolis from a Casino junket.
The aircraft was an Lockheed Electra. The problem was that an access door was left open by the ground crew. The vibration upon take-off led to a chain of events in which the crew became confused and basically forgot to fly the airplane. This crash was one of the impetuses for the Cockpit Resource Management (CRM) training program which is required today.
I remember this crash pretty well because two of the victims (husband and wife) were from the my small hometown of Ortonville, MN. It was a real shock to the community and I will never forget where I was when I heard about. Their son was a year older than me in school.
Here is a link to a television station website which does a good job explaining the crash and it's effects upon Aviation.
