Wow. 7 inches less than the normal 30 inches. I'm not a tall man, 5' 8'' to be exact, and I happen to have relatively short legs, my legs are horribly cramped on most airlines. Not the least of which is Spirit, of airlines I've ridden on, they are the worst yet in terms of leg room. Plus, what are people who are somewhat disabled, have a broken ankle or something, what are they going to do now if the weight is "put on the feet" I don't think I can stand on 1 leg for 8 hours. On a lighter note...the A380 has 800 some seats in an all economy configuration, you figure you could stuff in 1000 with these seats
