From about 20:00 tonight, looking from my house (Withington) to the north-west I have seen a strange sounding prop aircraft that has been circling over near mine at about 1500/2000ft but for the last 10-15 minutes it has been hovering much further north-westerly around Salford? or town? (or possibly the motorway) and at a much higher altitude, also spotted what looks like another prop circling around that area too. As of now the hovering one is still in the same point and all I can see is one white nav light and a flashing beacon, any ideas what it could be? Certainly doesn't sound like the MD902 or the BN-2 Islander..
