Second hand but from a close source.
1. SAR cancelled moments before the engine flamed out and a botched auto rotation resulted in the crash.
2. Well known chopper pilot who knew exactly where they would be was blocked from boarding rescue choppers and or flying his own to the scene, so when told approximately where to look they missed the wreck.
Well known local would have found it exactly. Sad state of "regulatory/risk averse" SAR procedures.
AMSA will get a message from me at least.
3. Pilot will not come out looking rosy if what I hear is found to be true, but the rescue should have been swifter for sure. No excuses. Lucky the boats found did what they did.
And yes a spider track or PLB would have been helpful for sure.
