How do you get to your seats up a ladder???, seat 2 in front of seat 1 will block your view, as will seat 3 in front of seat 2 etc etc, and as for the bird cages hanging of the ceilings, how do you get there, what if you need a pee, how are they angled to see the ice, or do you lay on your chest. How do they all get out, just open the floor and drop em all on too the ice. What about supplying everyone with wings when you enter, we could then all hover all over the place, and install 2/300 windows where we could just fly out at the end of the 3rd. Also we could build family nests, like house Martins do they would look pretty neat.
