One mechanic said the engines sounded like they were still in ground idle position. The surviving passenger said they didn't get enough speed to takeoff but he did not suspect any engine problems. Another ground witness said it sounded like the propellers were in very high or cruise pitch. After the accident both propellers were at or near the feather position.
