JFZ90 Greece isn't alone in its way of responding to the loss of the Helios 73.
The Tuninter ATR 72 that ditched off the coast of Italy was another case in point,a string of errors,a litany of systemic problems coupled with some imperfect decision making led to the ditching & the death of 16 people.
9 people in court,7 convicted, receiving sentences of between 8-10 years.
The Italian judicial system took the results of the accident investigation (which the ICAO says is all about preventing & learning) & used it to prosecute those involved. This was a travesty,but unfortunately (in the majority of cases) civil law is about blame & not justice.
