I have been watching out of my office window 2 helicopters circling over what looks like Thamesmead / Woolwich. They were there for about 30 minutes. One was a Seaking, one a Lynx but there were too far away to tell who they belonged to. So my question is, what would they have been up to ? Given they were deffo military, surely they wouldnt be allowed to be doing anything "security" related, thats would be police aircraft surely ? Does anyone know what Military aircraft are allowed to do in civilian airspace ?
