With the right electric field you can generate (a small amount of) thrust our of ions in air flowing over a charged plane.
One of the myth-busters “anti-gravity” devices they tested was actually (very weak) a static electric ion thruster.
Pretty cool - but it did need electric power input.
Sounds like he wanted to do a 1 man blitz, in order to reverse the outcomes of the actual ‘blitz’, but thankfully he turned out to be more of a V1 doodlebug.
