There is a new Iron Man trailer out that features the suit's flight feature. See it in the Project:Shadow HQ.

I can't wait for this movie. Only a little over a month to go till May 2nd.

This trailer is exciting with some new footage in it. ***Spoiler alert*** They show some new clips of Tony Stark testing the flight feature on the suit including a moment when the jets fail. We get to see him catch a car! There is also a very brief glimpse of a suit feature where his fist powers up for a powerful punch!
