National Airlines Flight 193, registration N4744, Donna, was a Boeing 727-235 en route from Miami, Florida to Pensacola on May 8, 1978.

An Eastern Air Lines jet ahead of them reported briefly having the runway in sight before losing it in the clouds and going around.

The aircraft was intact after the accident and was removed to a hangar at Naval Air Station Pensacola but written off due to extensive sea water corrosion.

The NTSB report concludes the controller "created a situation that would make it impossible for the captain to configure his aircraft in the manner specified in the flight manual".

Radar controller, captain, first officer and flight engineer all had indications of an out of the ordinary approach, producing a rushed and busy environment.

Similarly, the first officer never made the required 1,000-ft callout, because he never got to 1,000 ft mentally, because of his "inner time clock" which was based on a normal descent rate.

The lack of crew communication and a "no problem here" attitude resulted in false awareness of altitude and descent rate on the part of all involved.

Those passengers who knew or were told that the life vests were stowed in compartments beneath the seats had difficulty extracting them.
