What am I missing?

Well from what I understand is that they did it in a near vacuum and had force but they haven't done it in a complete vacuum. Also, I don't think anyone has tried to replicate this experiment. If, and it's a big if, it works in a complete vacuum, then we'll need another lab to replicate that result before anyone should run off screaming "We have impulse engines!" If it is a real effect, I don't know of any theory that would explain it as it's a violation of 1+ conservation laws.
