NASA's EM-Drive still under scrutiny

Some skeptical scientists are positing that the weak thrust from the EM-Drive might actually be an artefact. In other words, the EM-Drive might not actually work.

There's much more testing, repetition, and analysis to be done in finding out if this propulsion system works - and that is the way science should be, if we want to eventually move forward to finding a propulsion system that does work efficiently for the purposes of space travel.
