This was 6311's third day back in service after being stored out at MZJ since 9/14. 6311 was put back in service as it looks like 6304 may have retired itself at ICN from sever hail damage.

Yep. You're right. I think autocorrect got me on that one.

Organic matter (mangoes?) generating heat in the cargo hold? And this has happened before...

Not only is KDAL wrong, but there is no record of the diversion on Flightaware! Flight radar has it, just saying...

Looks like this may have been the jets first flight since it was returned from the bone yard.
