Wow, thanks for sharing.
It's always good to know, from the source, what happened.
So, this is what happened:
They took off from FRA to ORD, but they flew in the wrong direction, to the East. While over Romania, the mangos started to rotten and because the odors someone opened the cargo bay door, to let the "smell" out. All this happened without the knowledge of the pilots, and when noticing the warning, they declared the emergency and landed, thanks God, safely at OTP.
Right?
