I think that the "can't fly" folks have this in common: short attention span. If any post is longer than about 5 lines, they stop reading and immediately post their reply to the first 5 lines of the previous post.

All the scenarios countering their arguments are summarily ignored because the CF'ers never read them.

As a result, this thread is never gonna take off.
