> the aircraft propulsion method described in the patent is indeed possible

from that patent - they describe there spinning the 2m diameter disk at 30000rpm (ie. 3km/s edge speed):

"... we obtain an energy flux value of 10e33 W/m2. This exceptionally high power intensity induces a pair production avalanche, thereby ensuring complete polarization of the local vacuum state."

i believe it - 10e33 W/m2 can do a lot (it is total power output of a million of Suns concentrated into 1m2), and such EM field would interact strongly not only with the Earth magnetic field, it will do it with just sheer vacuum as well (that is the point of their patent is that vacuum isn't really a full vacuum according to QM).

So everything seems ok from the pure math EM/QM formula POV. There are i think only minor pesky practical details - like the material able to withstand 30000rpm 3km/s rotation while under the 10e33 W/m2 EM flux (the flux which would tear apart atoms and may be even protons/neutrons) and a compact energy source doing all that while fitting into the 2m diameter disk.
