Well this thread has sparked an interesting topic to say the least! Went on my flight aware of the NOTAM - kept a good look out but as suggested - saw nothing in the air! Only military sightings were whilst we were on the ground... First we saw a couple of tucanos on final for runway 27 at Dundee, and then a Hercules (maybe the same one as mentioned?) flying East heading out to the north sea, spotted flying north just past the high ground before Dundee as we drove home!
