[UGH HELICOPTERS. Hulk turns just in time to see Tony's suit go down, and NO.
NO!
The roar cuts through even under the chop of rotating blades, and he ignores everything else to make sure that there's one less helicopter to fire down at Tony. A leap up, and he catches one of the several helicopters by the tail, climbing up it as it bobs and weaves in the air. After only a few hand-over-hand grabs, he gets to where the blades attach to body, and rips the entire whirling piece off, tossing it over his shoulder and hanging on with his legs as the entire thing starts to plummet.
He's laughing as the ground comes up fast, and the impact doesn't even phase him, punching down into what's left of the helicopter with tight-clenched fists once they've crashed.]
