Thx, very interesting read!
On a side note: how does the system prevent the "cargo" from being windmilled by forward flight ?
Back to OT:
Sadly there is a high chance that the real reason for the mishap will never be published, especially as a police helos is involved.
In 2011 a "border controlling" police helo crashed into the Achensee on an sunny day, at close to Vne.
First reason was "bird strike". Due to lack of cadavers, feathers and witnesses having seen birds,
next try was "flicker vertigo" + epilleptic seizure, in a four bladed helo (wrong flicker freq) piloted by some w/o any history of such issue.
The transport Ministery hinted towards "cowboy flaying" on "sightseeing" or "alpine cabin-taxi" flights.
The Ministry of interior (opertor of police a/c) knee-jerkingly opposed.
Then Austrian Ministry ping pong sets in, denying existence of crash-analysis..:
Ministry suppresses security reports on flight accidents
Remember the 750kg bucket full wil concrete dropped onto an occupied cable-car cabin in 2005 (9 died)?
Still no accident report, investigation closed!
We are a Banana Republic of accident investigation:
"The ICAO found out in a topical report that the quality of the investigation of flight accidents in Austria behind those of countries like Botswana, Iran, Sudan, Russia or even Egypt limps behind. And it comes even more badly: Already in 2008 there was a similarly destructive result. At that time was of Doris Bures at the head of the department. A lot was promised afterwards, the flight investigation place was renamed, laws were reformed, but the acting people remained the same ones. Austria lies meanwhile far away from all European standards (even behind Greece or Bulgaria) – just still a thin percent point before Vietnam, Armenia or the Caribbean state Antigua and Barbuda."
