Question: As I always understood Ant-Man, he always retained the same mass, regardless of his physical size. When he reduces his size, he still retains about 160 lbs of mass, which makes him more formidable, like a 160 lb grain of sand. When he enlarges, even to gigantic size, he is still only 160 lbs. So, how can he kick vehicles around in the airport scene?
Question: Why would Tony be supportive of the SRA? In the first movie he revealed himself as Iron Man. In turn, he was attacked at the speedway by Vanko and almost got Happy and Pepper killed in the second movie. In the third movie, Happy is in a coma in the hospital, his Malibu home was leveled and Pepper was captured and injected with Extremis. Shouldn't this have opened Tony's eyes that by exposing his identity to the public, that he's now put himself and his friends in danger 24/7?
