You will also be aware that the investigating RAF Board thought that the aircraft was in cloud and not flying VFR at waypoint change.
The BoI may have thought this in 1994 but, as I said, Min(DP) admitted in May 2004;
“Unfortunately, we are not able to say, even approximately, how far the cloud extended over the sea”.
Thus, any conclusions arising from the BoI's opinion are invalid.
