Inside Stark Tower in Act 1, there are a man and a woman talking. They are at an angle from Wyatt Wingfoot [the guy who takes you to your next mission] straight across from the couch on Wyatt's left. If you jump at an angle towards the woman inbetween the man and woman and hold the analog stick in her direction, your character will jump, then stretch out his legs in the falling position and float a little above the ground. Sometimes if you stay floating like this long enough, an invisible force will catapult you away from the man and woman.
