When Adam repeatedly mentions the U-2's powerplant, he calls it a rocket engine. The U-2 is an air-breathing jet aircraft. The powerplant is a turbofan jet engine. As a matter of fact, it is the same engine used on the B-2 stealth bomber.
The narrator states that all the liquid in your body will boil away at 70,000ft without the pressure suit on. It's on NASA's website: your blood does not boil, you don't instantly freeze, and you don't explode when exposed to a full vacuum. There have even been experiments and accidents to back up that information.
The Mythbusters have a dummy set up with blue water running in it's veins to simulate blood. Adam comments that it must be a Vulcan (from Star Trek.) Vulcans have Green Blood. A better analogy would have been Andorians who do have blue blood.
