It's really frightening. Did the management spied on the Pilot's forum or did a "yellow" member forward the thread to his boss, the very result is that anybody will now think twice before expressing his opinion on the forum. It's not only a case for lawyers, it's a case for anybody willing to defend the very fundamental right of expression.
Not to mention the fact that some remarks under the topic "safety" did in the past contribute to avoid further problems in an airline strucked by two deadly crashes in the past three years: will a self-censure forced on the pilots endanger more lifes at Swiss International Airlines?
