An article at NasaSpaceFlight.com is claiming that the superficially reactionless EmDrive has again been tested at NASA Eagleworks, this time in hard vacuum, and the anomalous thrust is still being detected:
A group at NASA's Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum – a major breakthrough for a multi-year international effort comprising several competing research teams. Thrust measurements of the EM Drive defy classical physics' expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum.
With the popular explanations of thermal convection or atmospheric ionization being ruled out by operation in vacuum, and thrust thousands of times greater than expected from a photon rocket, is it time to start taking the EM Drive seriously as a fundamentally new form of propulsion, and possibly a door to new physics?
Roger Shawyer, the inventor of the EmDrive, claims that the device's efficiency will scale even further with greater levels of power, potentially enabling fast interstellar travel powered by a radioisotope thermoelectric generator or nuclear fission.

" so we've got this new navigation system. We've built it, tested it, tested it again, and now it's helping sail an expedition beyond the end of the Mediterranean past Gibraltar."" cool, how does it work?""nobody knows... We call it a lodestone, though."
This fucking thing had better sound cool.
I'm not flying with it if it makes a stupid noise, like how things sound in Star Wars Episode I. What good is a menacing star-destroyer with ion cannons and tail fins on the ass-end if it sounds like, "Boo-boo-boo-boo-boo-hee-hee-hee-heee!"
Are you fucking serious?!
I get a chance to fly in this thing I will take it even if it sounds like a fairy shitting itself politely...
But what if it sounds like Jar Jar...?
I believe that would defy the moral laws of physics.
