For us non-pilots, when you say "An inop ground station ILS which was not accounted for by the pilots.", I understand that you mean that the instrument landing system was inoperative for the two runways. What I don't understand is why that would not be glaringly obvious to the pilot as he made his approach, and how it might contribute to the crash.
Here is another news snippet I find interesting.
“San Francisco Fire Chief Joanne Hayes-White said the investigation has been turned over to the FBI and terrorism has been ruled out. “
—The Pueblo Chieftan
Why would the FBI investigate a plain old transportation disaster?
Now, if it ISN’T terrorism, then only the NTSB needs to be involved.
Here is an eyewitness report according to the Pueblo Chieftan.
Then all of a sudden I saw what looked like a cloud of dirt puffing up and then there was a big bang and it kind of looked like the plane maybe bounced (as it neared the ground), she said. I couldnt really tell what happened, but you saw the wings going up and (in) a weird angle.
Not like it was cartwheeling, she said, but rather as though the wings were almost swaying from side to side.
Eyewitness says plane was in an unstable state on approach.
