Original Note:
Though ion thrusters are capable of maneuvering spacecraft already in space and commonly do, they have limited applicability within an atmosphere https://www.scientificamerican.com/article/silent-and-simple-ion-engine-powers-a-plane-with-no-moving-parts/ Nonetheless, Newton's third law ("all actions must have equal and opposite reactions") has no bearing on the use of ion thrusters https://en.wikipedia.org/wiki/Newton%27s_laws_of_motion#Newton's_third_law
