I have to agree. As soon as I know there's a severe medical condition that could result in permanent injury or death, subject to wx/airport suitability, I'm diverting. High speed, mayday, ambulance on arrival please.
The captain must have had some very strong reasoning not to divert into Chateauroux, Dijon, Lyon, St Etienne, Clermont Ferrand etc etc. Perhaps he wasn't told of the severity of her condition? Perhaps there were TS/CBs elsewhere?
I don't suspect we'll see all the details.
