Re: iron Man's first flight or Superman's (MOS) first Flight?
Superman flight doesn't have the 'can we do that too?' moment because other than it's been done before in the 70's movie, Superman is a super powered alien. Almost everybody know Supes main feat is flight. Tony Stark is human, his achievement owed by his tech ingenuity and connects with the audiences more. If Stark could fly inside an exosuit, ordinary people someday could do too.
