"A team at NASA may have unintentionally accelerated particles to faster-than-light speeds while using the EmDrive resonance chamber... (...) ...few expected anything like this to happen: according to a post over at the NASA Space Flight forums, when a team of researchers fired lasers into the resonance chamber, the particles were accelerated to astronomical speeds...with some moving even faster than the speed of light."

"The NASA engineers also reported on the forums that they'd fired lasers into the EM Drive's resonance chamber and that some of the laser beams had travelled faster than the speed of light..."

"Posts on NASASpaceFlight.com, a website devoted to the engineering side of space news, say that NASA has a tool to measure variances in the path-time of light. When lasers were fired through the EmDrive's resonance chamber, it measured significant variances and, more importantly, found that some of the beams appeared to travel faster than the speed of light."

The posts subsequently disappeared - this implies that NASA did manage to accelerate laser beams beyond the speed of light.
