Blagger - how are ACCGS teaching the Vigilant T1 turnback? - in terms of sequence of actions, headings and bank angles? I don't recall that we ever looked at it in the clearance programme at BDN, but arguably that is a CGS task anyhow.
Backpacker - you're on, although I also know one of the research Test Pilots at NLR quite well, and I imagine he'd be delighted to come and work with you if I had a chat with him.
