I thought I knew a lot. I read the financial reports of all the major airlines. I recalled the financial details faster than Wall Street airline analysts. But I never knew the part about cargo and the 777's ability to carry a lot of cargo and the 787's inability to carry as much cargo. And with the air cargo business accelerating so much - that's a big deal! Humbled humbled humbled. Just goes to say... We should never think we know a lot about a subject as an outside analyst.
