Factual error: The Hulk picks up a tank, swings it around and hurls it about a mile away where it crashes into a sand dune. The impact should have been as strong as a plane crash, but a few shots later, they show one of the tank crewmembers standing casually outside the tank, watching the Hulk, as if nothing happened to them. All of the men inside the tank should have been seriously injured from the impact, if not dead.
Factual error: The jet aircraft that the Hulk hangs onto couldn't have flown as high as it's shown to. The max altitude of the F-22 is currently 50,000 feet, any higher than that and the pilot would have to wear a specialised flight suit. To see 'space', an aircraft must reach a height of 90,000 feet, which is almost double the 'safe' altitude for pilots, not to mention the F-22 lacks the engines of the SR-71 or U-2 to cope with the low oxygen levels of the upper atmosphere.
Factual error: When the Hulk is jumping from mountain tops to mountain tops, it is amazing at which speed he falls back on the next mountain. There is nothing wrong with him jumping very quickly at a 20,000 foot altitude (because he is very strong), BUT, the Hulk should not go down faster than a free falling object. Unless he has superman powers, falling from the top of his trajectory to the next mountain top should take something like 2-3 minutes. In other word he should not fall faster than the average skydiver.
Factual error: In the final duel between the Hulk and his energy-absorbing father in the remote lake, an aerial military task force drops a tactical nuclear missile on the lake, effectively sub-atomizing the Hulk's dad in an instant. While acknowledging that, yes, the Hulk himself might even survive a nuclear detonation, there is no doubt that the small lake (as well as Hulk's one-size-fits-all purple pants) should have been completely vaporized at temperatures of tens of thousands of degrees. However, immediately after the blast, we see the normal Bruce Banner drifting peacefully in the lake (which is not boiling nor even steaming) with his form-fitting purple pants entirely intact.
