"Worst of all is this statement from the paper: "Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust." In other words, the Cannae Drive worked when it was set up correctly--but it worked just as well when it was intentionally
disabled set up incorrectly. Somehow the NASA researchers report this as a validation, rather than invalidation, of the device."

"Carroll's final point - that the researchers measured thrust not only when the drive was configured to produce it, but also when set up to do nothing at all - may be the most important takeaway of all."
