CommentReturning from Iraq with Biggles but we didn't see them going in together. Judging by its callsign it was part of the team. The EUFI we saw going in with the MRTT was RFR9722.
So we saw Biggles go in with ZK349 and come out with ZK325. A switch appears the most reasonable explanation : ZK325 comes out and ZK349 takes its place in Iraq.
