Japan's two biggest airlines on January 16 grounded all their Dreamliners in the most serious blow yet to Boeing's troubled next-generation model after an ANA flight was forced into an emergency landing.

    Secrets don't make friends, Boeing. Earlier this month all Boeing 787 jets were grounded after battery failures led to unsafe conditions--and apparently Boeing was made aware of issues months earlier.
