Yes, got it thanks, Baz, it was superb and has been duly added to the manuscript for editing. Excellent detail and thanks also for the photos, I will clean them up in Photoshop and send back for your records. It's just been a tad busy of late here at work and I have not had a chance to write a decent reply...same goes for Altercumulus on here, who sent me an excellent email.
In general, a big thanks for everyone who has emailed, PM'd and posted so far - I value everything and am sorting it all out steadily... I will keep 'feeding' questions so please keep it coming is all I ask!
Baz, very quickly back to the oxy reg, bit of a daft question this, but in moving from the nav seat to the prone position, how did you manage at high alt before you plugged into the nose cone reg? Portable bottle or 'hold your breath?' I know it's not far as the crow flies between the two positions, but I was curious regardless.
