General,
Admit it dude. You want to be the biggest dog in town. That's patently obvious to those on the outside. You spend an ungodly amount of energy sifting through the net trying to find ways to discredit other airlines and prove Delta is the best. Do you stop to sign autographs in the parking lot after your European trips? Tell the kids about all the hot "stews" and the ice cream sundays at FL350?
Yes Typhoon pilot wanted a job back in the states. I bet he had his fun, has a nice sum of cash in the bank, and is ready to go home. He probably can't just up and retire so why not take a job with Delta for the medical insurance, paycheck, etc. But I bet you his financial security is pretty solid. I imagine he has some pretty great stories to tell his grandkids about flying all over the world. Not just back and forth on the NAT tracks in a clapped out old 767. And he got to enjoy being a 777 captain in his 40's, maybe even 30's. Spending 40 years at one company is not necessarily the most fulfilling path to take in life.
