LW,
I'm pretty sure that doesn't apply to the pilots under training. They may not be out of the RAF until Sep 11, I don't know, but I believe they will be selected, or de-selected, about now, and cease flying training.
I believe WSO training has already stopped, and those WSOs that were already in the pipeline have been told something along the lines of they are up for rebranching or redundancy, probably the latter. But my knowledge of that is incomplete.
