It is in character, but I think Thor could rip the ground itself free. True, he'd be stuck to a chunk of floor, but he'd be relatively free. I'm not sure if Iron Man has that kind of brute physical strength. Though, with a few missles, he could likely replicate that feat. I wonder if a Static Cling could stick the hammer to the floor, making it ironically difficult for Thor to lift? Doesn't Hal have a sort of personal force field? I don't know exactly how effective it is, but surely it'd provide some protection? I'm not sure if Static would succumb to a few missles; he's been shown to be able to stop bullets after they've been fired, and missles, while potentially faster, take a significantly longer time to accelerate to that speed. I think Static could deflect or block missles from Iron Man. Another thing: how sure are we that lightning would do anything to Static at all, or that Static's electrical attacks would harm Thor for that matter? I don't know, Hulk was hitting Thor pretty hard, and he never really went down for the count. I mean, he probably would have fell to Hulk eventually, but I'm not sure if Lantern's constructs were on a Class 100 level of power. I disagree about Thor being too busy to help Iron Man. All these guys would be fighting in the sky, it's not a stretch to assume both teams would be working with their partners, even if only a little. Also, keep in mind that Static can boost Lantern's power the same way Thor could boost Iron Man's.
