While monitoring Heathrow on Sunday evening (12/01/2014) at approx 21:00, there were duplicates of SAS1501 overlaying each other approaching the airport. Looking at the display for each aircraft they were being tracked by 2 radars (sorry I haven't supplied a screen shot).
Why were 2 radars reporting the same aircraft (OY-KAN) at the same time? Surely only the latest data should be displayed?
