The Ars Technica video Astronaut Scott Kelly teaches orbital mechanics with Kerbal Space Program (also in YouTube) is a little bit humorous.
When Scott Kelley is talking about orbit circularization he says (per the on-screen captioning):
Actually the Space Shuttle has two Ohms burns generally.
Question: What are Ohms burns, and why are two needed?
Ars Technica's Lee Hutchinson sits down with astronaut Scott Kelly while they play Kerbal Space Program. Scott Kelly uses his experiences on the real International Space Station to give his opinion on the accuracy of the video game.
