Factual error: When Catherine's father walks through the corridor of the military base, on his way to the first test of the flying Hunter Killers, he is accompanied by a female civilian employee who is wearing a yellow blouse and you can see a fair bit of cleavage. Civilian employees on US military bases are required to dress modestly, and she is showing too much cleavage. The US military is utterly rigid in imposing their dress codes on civilians and she'd be ordered to button up.
Factual error: When Arnold is done shooting at the cops in the graveyard scene, there are birds singing in the background. No way that any birds would be left in that area (not to mention singing) after at least 15 machine guns have been firing for more than 2 consecutive minutes, not to mention the cop car exploding.

Factual error: All over the particle accelerator you can read about the dangerous magnetic fields that are caused by it. the radiation that is created by the accelerated particles is mentioned nowhere although there is no possibility to find a wall without radiation warnings in a science lab with a real accelerator.
Factual error: When the T-X is driving the crane and swinging the Terminator around, that is mechanically impossible. All mobile cranes are designed to run only when they are in neutral. The T-X would have burned out the hydraulic pump within seconds. (00:33:50)
Suggested correction: The TX can control other machines including police cars, it's not far fetched she could control and manipulate the crane truck in anyway she wanted.
Being able to control the crane truck does not alter the fact that the hydraulic pump would burn out. That's the purpose of the safety system.
The T-X is a super robot from the future with machine controlling superpowers. So she presumably overrode the hydraulic systems in some techno magical way. None of the Terminator movies are particularly mechanically realistic so this shouldn't shake our willing suspension of disbelief.
I can't answer for every single model of crane as I imagine they all vary, but we have a Demag AC45, a Bocker AK46 or our Manitou 2150. We can operate the hydraulics whilst in motion and we've never once had a problem. That being said, we're not doing 30MPH at the same time as using them, might very well be a different story if we were.
Factual error: During the scene where the Terminatrix remotely controls the police and rescue vehicles, we see the police car's shifter drop one notch (from park to reverse) but the car takes off going forward, throwing a cop out. (00:28:55)
