I agree with 99% of what you said, Cap. However, I want to stick up for the last design, as that is a really solid logo and shows a lot of restraint with the highlighting. Also, the second to last logo is supposed to be three jets in the shape of a maple leaf (originally a Winnipeg Jets concept); if you simplify that down to one jet and eliminate the trails, it's pretty close to the simplified designs you have in the second part of the post.
Let's also not pretend that some of the less-complicated logos are very good either. There's strength in simplicity, but there's also a reason why many of those marks are only pieces of the logo and not the logo itself. Hats off to the Memphis Express brand.
