Nunc, I too am sorry for your loss.
Mick Smith's post and Flip's highlight what went so badly wrong regarding airworthiness and what is hoped to be achieved in the bigger picture by highlighting Sea King mid-air collision now.
If I was the Coroner I would be hopping mad if there was evidence from a prime witness of;
a. Collusion
b. Willful failure to implement airworthiness regulations.
At the very least, I would move to ensure that I heard the new evidence from the witness. The only way this can happen is to re-convene either the BoI then the Inquest, or simply re-convene the Inquest.
Many of us have conflicting views on this collision. The most important views are those of the Coroner and the BoI. If they are going to be prevented from seeing this this evidence then one can state categorically that justice will not have seen to have been done. And the families might be condemned to live with the element of blame lingering in the air unnecessarily.
I fully expect to see some developments in the coming days and weeks.
