Thank you for your tip
While you are , by virtue of considerable experience, qualified to comment on the operation of a Trinidad in domestic eurocontrol airspace, I would suggest you have very little experience in the reality of transoceanic ferrying operations, and should therefore comment (or not) accordingly.......
but unfortunately you have undermined it considerably by suggesting that you think the following (which may or may not have happened on this flight) is OK:
I think it is much more likely to be a pilot decision making accident. He probably launched with a considerable head wind which was scheduled to diminish, a not unusual situation at this time of the year, ....but did not and he paid the price.

I have never come across a wind which is "scheduled to diminish". Where do you find those, and where does the wind publish its diminishing schedule?
Having done a number of 900nm+ flights (no ferry tanks) e.g. UK to the bottom of Sardinia, I know a little about fuel planning too.
Also, accurate fuel gauges (no fuel gauge can be that accurate, being just a small analog gauge) are of little use when you are say 1000nm from the nearest airport, over the sea. The best you can read a gauge to is about 5% and that assumes zero errors elsewhere. The 29.5 and 30.1 outcomes mentioned were just pure luck because nobody can read these gauges to that accuracy - of the order of 0.1 to 0.01% of full scale deflection.
