Not from me, certainly. We saw that the Chitauri fliers were capable of causing the Hulk pain if they could deliver a massed barrage of fire. If Thor was fighting on his own, he'd eventually get overwhelmed and worn down. Sure, he could hold them off for a long while, but the kind of moves he'd have to do to break up their forces would indeed be collateral damage heavy. And that's not reckoning with the leviathans: I suspect having one of them slam into him would be not-fun.
