ADELT = next to useless IMQHO. No replacement for real time tracking.
I also think regular cold eye reviews are a useful tool in these organizations - no vested interest BTW. SAR orgs, often have a fearless response culture......not all but some. I think it would be some comfort to be able to say "we are aware of the risks and have regular review of our Modus Operandi" to keep those cultures objective.
Above all RIP to the crews and thoughts to the families.
There but for the grace...etc.
