Mike. I can understand your position however I ask a question on behalf of one of the families involved .
Have you considered that if you had a radar screen in front of you that night it would have been obvious that the pilot was heading about 90 degrees off the correct course after leaving the vicinity of CRAVEN.
If you did have access to radar and you had advised the pilot 20 minutes before the crash of a more suitable heading do you think there was say an extra 10% chance you could have prevented the accident?
And if Mike does not wish to answer perhaps another ex FSO could.
