A Squared:
According to the NTSB, The tower controller on duty reported seeing the aircraft's landing lights prior to the crash.
Indeed, Mr. Sumwalt stated that.
Nonetheless, that is not a factual statement. Mr. Samwalt relayed to the media in his press conference what the controller claims he saw.
Fair enough for press relationships.
The switch positions are factual. I presume they were all documented faithfully since the cockpit did not burn.
