Everyone had to start somewhere
Correct. Somewhere like an aircrew selection centre where only a small percentage make it through followed by months of leadership and ground-based professional training designed to reveal unwelcome character flaws and suitability for flying training. Then a year or two of basic flying training, operational conversion on one type or another, squadron-based operational flying, SAR pre-selection, then a lengthy, exacting SAR course with a high chop rate followed by SAR operational conversion and squadron acceptance.
Or you could bypass all that flying selection, training and experience and just get lucky when some gaps need plugging.
UK SAR will work because SAR crews are passionate and dedicated to make it work!
I think it will take a little more than dizzy optimism and blind faith.
