We've never seen ZK323 before but that's not surprising. It's flying in for the first time so no mystery.
But why haven't we seen this one, ZK358, before ? It's flying out of Akrotiri surely we should have caught a glimpse of it by now. Unless it's been just standing around at Akrotiri the whole time. So, what gives ?

It turns out that until yesterday it was in Coningsby, like ZK343.
That means it flew into Akrotiri today, just before ZK343.

But then why is it flying out again ? It isn't here to practice a touch-and-go at Akrotiri and fly back to Coningsby, right ?

@ 19:23 UTC : I'm pretty certain it did not land at Athens airport -- although it's not impossible -- but it is certain it landed in Greece -- Elefsis or Stefanovikion.
Now that is "curiouser" : the RAF has a whole base equipped and experienced to handle EUFIs, why send the new arrival to next door Greece ?

ZK323 flew into Akrotiri and stayed there. Interesting little fact : it's callsign was RRR9711. Familiar ?
Indeed, well spotted grasshopper : it is the 'Ascot' (RRR) version of the callsign used by the EUFIs flying into Iraq from Akrotiri : RFR9711.
