Hi,
I'm not a professional pilot (only a recreational one) so I'm talking out of ignorance, but...
Why did the flight crew decide to make an unscheduled landing in France (or an "emergency landing" as the newspaper put it) in such case?
Announcing to the passengers that the windscreen has cracked can cause some of them to panic and do stupid (and very dangerous) things. Doesn't such danger from passengers outweigh the danger of carrying on to the final destination without telling anyone?
