Concerning the Penta incident at LHR there should, in my opinion, have been a full incident/accident inquiry by AIB.
AIB would have drawn conclusions and made recommendations on an impartial basis.
If AIB had commented that the flight had been operated in a negligent manner then it would have then been reasonable for the case to go to court.
The jury would then have had an unbiased view and made their deliberations accordingly.
In my opinion this case was a travesty of justice.
