Too close for comfort??
For the second time in two days I've had an aircraft come a little too close for comfort. Flying in the Vale of York today in a C150 on a constand heading an aircraft overtook me from above (around 250-300ft above me) and then began descending through my intended path from around 2000ft into the visual circuit at X airfield. At the time I was receiving a FIS but didn't receive any prior warning about the traffic. The guy clearly wasn't in contact with any unit and I proceeded to land at the same airfield. When I approached him he stated that he didn't even see me and never knew I was even there! What could I have done to prevent this? I was in a high wing a/c so I could only see him once he was in front of me. Would I have been better having a RIS? Did I let him off too lightly? Anyone had any similar experiences?
Thanks
