They teach me something I know nothing about but care very much. Sometimes I have a hard time comparing the differences in the planes. Like, what is important and what is not.
All I know is, I will NOT fly on any of these large aircraft. It is getting insane. What next, an aircraft like a cruise ship with 4,000 people on it?
The next generation 747 shouldn't be an issue; it's built around a well established airframe.
