Here's some eyewitness testimony about another engine part, not the Murray St. one. I was incorrect about the woman, she was injured (crushed) by landing gear, not engine parts.
'We just passed a compact car where the engine was running and the door was open, which looked to me like the driver had escaped, but from the back seat to the trunk was crushed by a jet engine. We started going up West Street. I believe that's when Smitty ran over the part of the plane, but he did that to avoid the bodies because there were obviously bodies in the street. FDNY firefighter Michael Hazel
There was a car that we drove by that the driver's door and the passenger door were open, and there was a plane motor on the back half of the car. Two inches more, and both these guys would have been dead too. That was their ticket. It was amazing. The car was actually cut right in half with this motor, right there back of the front seat. I sat there in amazement. FDNY firefighter Richard Saulle'
