The report does not yet state why the pilot aborted the landings: it may
have been because of lower-than-reported visibility at the runway (such
as a small fog bank), or simply difficulty flying the approaches (such as
drifting too far off the LOC or GS and deciding to go around each time).
There is no mention of mechanical problems or fuel exhaustion, but that
might still be under investigation.

One more point -- the FAA report that I posted earlier stated that the last
clearance issued was to fly heading 230 and maintain 3000, so the plane was
likely being vectored downwind to rejoin the ILS 5R approach for the third
pass. Given that the ceiling was 800 BKN, 1800 OVC, the plane was probably
in IMC at 3000 ft when it suddenly dove under the radar.


All the best, and fly safe,
