Well - the positive thing is that this report should kick into touch the current CAA obsession for ELT to be fitted to all helicopters! If this machine had an onboard ELT, it would have sunk with it and left the Chilean Navy searching a "last known transmission" - whilst the crew would have been pushed well away from the ditching by the tide and high winds. Personal ELT (and sat phone) saved lives.
Some figures in this report just don't stack up: "440 nm crossing", "groundspeed 120 kt" : this would mean landfall in less than 4 hrs.
"Just over four hours later" (after departure)......
"Their flight plan specified an endurance of 7 hrs 30 mins."
And the big one: "The pilots would not provide details of the amount of fuel carried on board......"
Tanks for the memory.
