Semantics guys: Wake up and stop splitting hairs will you!

This cab departed its intended flight path because the pilot(s) allowed it to - FACT.
When a helicopter experiences a:
combination of
the nose-high attitude, low airspeed, high rate of descent
and high power placed the helicopter in a vortex -ring state entry condition (VRS)
.....trust me implicitly when I tell you this, but it is in IVRS - FACT.

Aircraft rarely crash as a consequence of departing their intended flight path, but without a suitable height for recovery, they will always crash when in IVRS or VRS.


When the IVRS became established and it DID become established in this report [placed the helicopter in a vortex -ring state entry condition (VRS) ]
The pilot was committed to impact the sea.

Stop fiddling around the edges the lot of you. IF you have ANY understanding in the field of helicopter aerodynamics, you will see this for what it is. Plain and simple.

* I know dozens of pages have been written about cockpit warnings/autopilot playing up/repeater lights, etc. but the final report will leave absolutely no doubt whatsoever about how this accident cam to be.
The CVR and graph telemetry will see to that.

Double Bogey: You really worry me....................................
