What type of plane is continuously flying over the Southport area this afternoon?

This afternoon there is a very large, "heavy" plane flying continuously over the Southport area. Is it a Nimrod on manoeuvres or perhaps it is being tested? It is very unusual to see a plane of that size flying so low for such a long time.|||It is a Nimrod, you said so yourself.|||I'm not too sure but I live in Fairfield and see aircrafts (even commercial jets) flying above my head every half an hour. We know that there're 3 int'l airports in NYC and a bunch of regional airports around here. Plus a load of rich people here who drives their planes for fun you know.|||It's practicing chemtrail spraying drills so that once the New World Order of evil politicians give clearance, it will dump barium flakes into the sky for the purpose of keeping the common people dumb and serving the elite class.|||its a large drone and its looking for osama bin laden/stay away from any arab looking guys that are 6ft5in
