I'm rather new at this. I was about to suggest that it was a heli as it did a 180 deg. turn.
It has now gone from the display, but did display what looked like a German cross in the flag column.
It arrived from France east of Exeter, then NE towards Yeovilton, but turning right to miss Lyneham. South of Fairford did the 180 deg. turn.
It was then shown as taking off. Last LL: 51 29.9 -002 02.8
Did it disappear as it landed at Lyneham, as it approached the runway at almost 90deg. ???

While typing, I've just experienced my first Army Apache fly over my house while AirNav has been running. Just why I bought it. Now to get an early warning set-up.
