What's the status of Abramovich's 767 - P4MES

Abramovich’s 767 (P4MES) is listed on Flightaware as having last flown from Rochester, US to Stansted,UK on 24th February - which it did! However does this mean that it is still at Stansted and unused? Surely not?

We don’t have GA flight tracking data outside the US and Canada, so it could have gone on from Stansted to anywhere.

OK Thanks. However, up until that flight I had been tracking previous movements, through your live flight tracking, mainly from Moscow to Stansted then Aruba and return.
