Sasless, you have as we say, 'got it in a nutshell'.
If I may add my few pennies worth: I spent years, banging my head against a brick wall combination of management and CAA personnel who were convinced that a non-CAT 'A'/PC1 takeoff or landing was a dangerous takeoff or landing. So we ended up with HEMS pilots reversing out of HEMS sites, nicely into wind, over the top of children's trampolines, building sites and sometimes, even the HEMS site etc.
At the same time, talk of military ITO combined with civilian HEMS operations is probably not sensible, I say this on the basis of the number of ex-military pilots, who have been involved in fatal incidents and near misses because they had 'done them before' (back in the military days) in unstabilised aircraft. Generally, the event has occured following a lack of recency, training, briefing or organisation approval. Would I have taken off in the conditions that appeared to be present in the video? I think probably not. Would I have reversed towards potentially the biggest structure around? Definitely not!
Cheers
