Doc - I believe it is all the stuff that was promised to be on the aircraft when they arrived - if you make a list of essential kit for night over-water ops then quite a few shortfalls will be on it.
So who is to blame? Manufacturer, Contractor, Sub-contractors, operating authority? Whoever is responsible for putting the aircraft into service in an unfit condition - at least the crews did the right thing by saying enough is enough
It's just a shame they had to be put in that position in the first place.
Will SAR post 2012 be this badly managed? You need the proper kit, properly tested and fitted to do SAR, not the future promise of some ill-defined capability that looks good on paper and keeps the accountants happy.
