Flight diverted to KBGR based on comment of one of the passengers according to MSNBC
What was said?
Apparently it involved a bomb threat. The passenger - an American citizen - was subdued by air marshals
Lots more info here including video of the plane landing:
Quit flying A330’s and it won’t happen… 
What the passenger actually said was: “An Airbus?! I may as well just strap on a bomb! We’re all dead…”
Or something like that 
No, if it’s an Airbus he don’t need a bomb, they’ll all be dead anyway… 
Ouch, guys.
I’m definitely seeing a correlation between Delta’s Airbuses and crazy people. I knew we should have immediately gotten rid of them.
Yes sir…
The flight continues to KATL with a different number, DAL9901
ROFLMAO
