What ever, the OP does have a valuable point though theres an aweful lot of unusual air activity recently, I can only guess but suspect it may be something to do with the French getting RAF support in Mali, or our spooks trying to get assets in place near Benghazi to extract any stuck Brits?

Nearest I can find out that may help Prepaday is that the local authority may be using aerial recconacance aircraft to do a survey of your area , In the SE they are looking for garages converted into residences for illegal immigrants, up north I think they may be looking for conservatories and pools so they can bump up peoples council tax bands next year for having the audacity to improve their homes??
