Personal opinion here:
Am wondering if Airbus Air France won't be in a heap of trouble (not to mention France itself, given that they're major shareholders of these entreprises), given what I've been reading. (Major media silence in France up till now.) Bad, bad news.
Good commentary here from someone who knows way more about airplanes than I do (thanks, Dad).
Air France pilots are considering refusing to fly the A330s and A340s that haven't had the instruments in question upgraded, according to Le Monde.
