Okay, time to post scans of this, since most dismiss it as nothing when there are still billions of tons of mountain that he's bracing above him. And trust me, bracing is almost as hard as fully lifting, so the difference is slight at the most.
To get an idea of the mountain involved, it Dwarfs the Andes
"Underneath Billions" so it may not be 150 like the cover said, but at THE LEAST 2 Billions.
Under 2 miles of Rock, could be Hyperbole, but considering the size shown above it could be a bit conservative.
These 2 scans show that Hulk could have easily gotten out, if he let everyone else die. He was bracing it for them, not himself. He also got hit by the mountain dropping himself. Iron Man might have helped a little, but considering the sizes involved (Iron Man is braced at the back as well under Hulk's arm) Hulk's got the vast majority.
I hope this has educated a few, and I will try to repost these as needed.
