In the post-credits opening of Iron Man 2, we see Tony Stark jump out of what appears to be a C-130 transport aircraft to air drop into the keynote address of the Stark Expo. Now, my question is: why did he have to be flown in? It seems to be vastly cheaper and more easily timed to just have him take to the air away from the venue using just the suit. I'm not sure the audience even realized that he just did a variation of a HALO jump so even flying in through the roof would have accomplished the same effect.
Is it just for Rule of Cool? It does look pretty amazing when you don't think about it too hard, which I guess goes for most of the movie, but I'm struggling to think of a reason, in-universe or not, for flying him in.
As I recall, a trailer had Pepper Potts in the plane with him, but I would imagine them typically preferring their private plane over the sparse interior of a Hercules.
