I agree with you in that Vol. 3 seems to veer off of the topic of flight, but I don't think any of the stories in Vol. 3 are shitty...just not on-topic. The one titled "Polaris" is currently my favorite, although I loved the one right at the beginning, "Underworld." I'm really, really enjoying all of these. Hopefully some of the artists represented will be at Comic Con this summer, I'd love to see some more of their work.
