If Bond are going to use line co-pilots, that isn't too much of a problem so long as there is a training scheme in place for them to become SAR qualified. After all, you have to start somewhere!
Are the HEMS medics going to get a winchman's course from someone such as Bristow, FBH or the RAF? If not, how are they going to be trained, in house? Will they be able to get recurrent training to keep up their medical skills? Anybody know if Bond have any SAR trainers on their aircrew side, or are they looking for those too?
I suspect that there is a lot going on that we are not privvy to for whatever reason (probably commercial) and only time will tell how it is going to work. Fun to speculate though.
