They have been working on automated ATC for a lot longer than 20 years. I worked at Eurocontrol 1991-1996 where they had been developing a system called ARC2000 since well before I arrived. As the name suggests it was intended to take over ATC in Europe by the year 2000. I worked on a less ambitious system that helped visualise conflicts for manual resolution but that was not a big priority so I eventually left.
This summary misses a lot of recent developments in the case that were published recently in a book "Jeanne Calment, the Secret of Longevity Unravelled"
New evidence includes examples of signed documents showing that her signature changed suddenly in 1933, about a year before Yvonne is supposed to have died. There is also testimony from the family of a doctor in Switzerland that it was Jeanne who was ill with tuberculosis in 1931, not Yvonne who had recovered by then. There is also analysis of her recorded interviews showing that she often spoke more like Yvonne.
Aging does not work like height. There are several biological processes that contribute to aging so one gene mutation would not make someone live longer. We can make people taller by giving them growth hormone. If aging was as simple we would have easy ways to slow aging by now.
The records dont confirm that there was a open casque viewing, but if there was, how recognisable is a mother vs her daughter if she just died of tuberculosis? In fact the funeral was very fast. She was buried the day after she died.
Living seven years longer than anyone else had before, and three years longer than anyone else thirty years later is too good to be true. Evidence such as a sudden change of signature show that Jeanne Calment's daughter Yvonne had assumed her identity.
