Jets work on cylero?

they will work ingame technically, however even the most powerful ones wouldn't have enough TWR to actually fly @FriendlyFin

@Zenithspeed
how about a tenuous atmosphere that is 0.001% earth’s?

yeah as said below, they do work on Cylero too (more specifically, any planet with an atmosphere), however due to the low density of its atmosphere you need a lot of base power to have enough TWR to lift off there

@SmurfResearchX hm might have to research that

yes - it has a much less dense atomosphere, so performace is similar to high altitude on droo
