Re: iron Man's first flight or Superman's (MOS) first Flight?
Iron Man of course.
Superman flying through the sky/hitting the mountain looked really pointless. Was he practicing to fly, was it done to add another CGI-fest scene in the movie, I don't really see the need of it for the story. I also felt like he just flew away because he got his Superman outfit.
Me. I Am Psylockolussus... The Elusive Mutant.
