As far as the 72 in ORD, it did land short and then bounce to the runway and settle off to the side. The tower did in-fact let two airplanes land on the same runway. One aircraft landed and taxied in and the other did touch down but went around. It was an airport vehicle that discovered the AA flight on the side of the runway.
The FO was PF until they reached min's and then the captain took over, per company policy. It was still coupled when the captain became PF. It began to sink below GS, the FE noticed and the captain tried to apply power and that is when the plane struck the ground. There was a sound on the cockpit voice recorder that sounded like the AP being disconnected but the captain does not recall disconnected it. One thought was that he bumped in when he took control on the aircraft from the FO.
The autopilot was timed for a slower approach speed but they came out with a new procedure to fly faster and never adjusted the AP. So that could have been one cause of the accident. I do not recall what the FAA actually came up with after the investigation.
I do know that other aircraft had reported discrepanies with that approach. The FAA did functional tests after the accident and found no interference from anything. There was a TV station close by that they thought might have caused a false signal. There was no interference from that found either.
