No, but I may have trained them in a previous life
DB - you do need a bit of a reality check with regard to what was being done here - you have absolutely no idea what task they were on.
HEMS might not be allowed to do this but UKSAR operate under EASA rules, under CAP 999 and they would be allowed to operate like this to save life! However, I'm with Paco and, if you are the only asset, and you have the ability and training to mitigate the risk, then save lives if it is possible.
I, like many SAR pilots, have had to turn down jobs or turn back because the rescue was simply too dangerous but a straightforward hovertaxy in cloud with decent references and an escape route/IF option really isn't that risky.
And a lot less risky with many of the modern types with excellent positioning systems, advanced autopilot functions and deicing providing more and safer options. These have certainly brought changes in SAR and this role will be little different.
