After we figure out how to increase the mass of our atmosphere 90-fold, maybe. Venus is around human body temperature at the altitude where atmospheric pressure is similar to Earth's.

The most Earth-like environment on the Solar System (other than Earth, of course), ~50km high in Venus[0] :) And to think that humans could've gone there...

  Iirc, the second-most human-like is Saturn, where there are zones of warm air at around 10atms, which is manageable for humans. Not as radioactive as Jupiter, but you can't float a zepplin in pure Hydrogen. Also, the wind speed would obliterate any aircraft.

    You can. Just you need to go the route of a vacuum airship instead. Or go for a hot helium balloon. While admittedly science fiction, The Clouds of Saturn by Michael McCollum explores this a bit.

      Now I want to build a hot hydrogen balloon. Put some drone motors and rotors on it from control. Then one day land it near an open flame.

        Well, on Saturn thered be no oxygen to combust, so hot hydrogen could work, maybe (I'm suspicious that it would be able to lift the heat source much less the equipment). Hard part would be fuel to heat it.

        A chemistry professor that I was acquainted with did this as one of his lecture demonstrations. Shakhashiri (and he's still doing it - http://scifun.chem.wisc.edu/BZSPresentations/Presents.html http://scifun.chem.wisc.edu/BZSPresentations/Presents.html Once Upon a Christmas Cheery, In the Lab of Shakhashiri is going on its 47th year!). https://www.youtube.com/watch?v=_tsgh_T59gE https://www.youtube.com/watch?v=_tsgh_T59gE has what you are looking for (at 3:42 though you'll likely want to start a tad bit earlier).
