how do you know this? Are you one of them super secret world government feds? Are you an ayylmao?

why should i care?

WRONG because magnetohydrodynamic engines, while able to accelerate propellent fast and therefore having high specific impulse and efficiency, do not have high thrust and so are not a practical engine for use on landing or atmospheric reconnesance craft. However using a magnetohydrodynamic generator to turn heat from your reactor into electricity would be a big improvement over using a traditional turbine design so in that sense they might be used.

If flying saucers were real they would have to use an exotic engine that isn't a rocket or they would burn everything beneath them when they hover.

Probably a dual engine system for different applications

An MHD engine would be really underpowered for an alien spacecraft tbh, they are great for where we at today but even then I see them being fairly quickly made obsolete in most of the fields they are best at by fission fragment engines. You wouldn't get between star systems in any reasonable timeframe using them.

Realistically flying saucers would probably be helicopters since that's the easiest way to have a big object hover without glassing the ground beneath it. Maybe they just look like saucers because they have wings on their sides which are spinning really fast.
