Executive summary: NASA determined that the “thrust” produced by the Em Drive resulted from the interaction of the drive current with Earth’s magnetic field. Too bad, it would have been lovely if it had proved out, although it would surely have caused some difficulties for physics.
I feel that the true results and their implications are being presented in a perpendicular way. The drive current does produce a thrust in some circumstances even if it is against the earth’s magnetic fields. That can still have some potential applications. Applying a strong magnetic current( like maglev trains) to a metal based rocket launchpad and applying a counter current emfield from the rocket or ship might help do a virtual reduction of gravitational pull and give the ship a “boost”...even if it isn’t going to be useful as a ftl drive.
Someone wants this quashed. Politicised NASA pooh-poohed this...so consider the source.
