Baron Harkonnen was so overweight that he requires anti-gravity devices known as suspensors to support his weight.
Did anybody else have suspensors to help them float or fly?
Such technology would have helped people out in the deserts to evade sand worms. It would also have helped the Harkonnen soldiers when the Fremen attacked. Looks like the Harkonnen family did not equip their own soldiers with such useful technology.
Despite the practical uses of personal suspensors for combat and survival, I don't recall seeing the technology used by anyone else.
I have not read the Dune series in decades, so I can't recall if anybody else had a flying suit. Please provide answers based more on the books than the movie or the TV series.
