The second diatribe was from a failed ex-Delta pilot who was also fired from Delta for fraud. He certainly had some valid points but was a real pain.
It sure wouldn't be the first (or last) time that a fired pilot suddenly reinvents himself as an 'aviation consultant'.
"I couldn't do my own job without getting canned - pay me to show you how to run your operation!"
Some of the folks who pop up with sound bites on CNN and the like after an aviation incident have very colorful employment histories.
Anyway, the 'Delta Audit of Korean Airlines' has been sighted (and cited) more than Elvis but no one seems to really have a copy after all these years.
