Biggles exactly where you would expect doing exactly what you would expect : holding pattern West of Erbil.

@ 13:31 UTC : Returning but with a different Jetson/EUFI ! They pulled a switcheroo ! Biggles went in with ZK319 and comes out with ZJ950 -- a different type of jet even.

Unless we didn't see ZJ950 going in with the pair and now ZK319 is the invisible man.
