Soviet era aircraft at FUE

At home on the Isle of Wight, an hour ago, we heard an unusual aircraft.
It was Antonov An-12BP, Ukraine Air Alliance, passing only a couple of miles to our east.
Unbelievably, it came from Fue.
According to FlightRadar24, yesterday, it flew from Luga (Leningrad), to Hannover, then to FUE.
I tracked it till it went quiet just before Birmingham.

What were the chances of spotting that?
