Cazatou Reality. An excellent example of an oxymoron.
Olive,
If what Caz says is correct, the crew did not commit their act of negligence close to Waypoint change. They did so the moment they decided to fly the mission. They, the Authorising Officer and anyone of Rank present, who did not attempt to stop them flying are all guilty of negligence.
Now since the BOI, PAC, FAI,HOL, even Wratten and Day have never said the crew were wrong to attempt the sortie, perhaps it is you that require the reality check.
