<<Please enlighten me - was it a lost pilot?!>>
Applelisa... Big aeroplanes don't get lost! Everything going on round that area is under radar control anyway. You're only just over 5 miles from the runways so aircraft would be quite low over your place under normal procedures.
At that time at night traffic may be dropping off and it was good weather so the pilot may have opted to do a "visual approach" from some distance out. This might mean that he would not be on the usual final approack path and possibly lower than usual - ideally at your location he'd like to be around 1500 feet.
I doubt that it was anything really unusual.
