And odd ones

• TUAF304

The K35R, 60-0343, moved away while Biggles, RRR9422 is moving toward the regular holding spot the TB2 is now practically occupying.

The RAF MRTT aka Biggles is not moving towards Erbil despite my handy directions with arrows etc. The TB2 is getting the free range as they all studiously avoid noticing it.
