In addition, tests were conducted with a DC-3 airplane after squirting about 3 gallons of water into the four brake drums. The wetness of the brakes resulted in no perceptible delay in brake action.

The evidence shows that the flight was properly dispatched from Pittsburgh, Pennsylvania, and that it was properly conducted up to the time that the landing at Morgantown, West Virginia, was begun. It appears further, that the weather conditions at Morgantown were above the prescribed minimums and satisfactory for a landing at the time.
It seems apparent that the probable cause of the accident is to be found in a combination of several factors. The evidence loads us to
