I'm not sure if this has been addressed, but I know that the gas giants in our system have pretty incredible wind speeds. I think Neptune has the fastest, with winds over 1000mph. Do you we'll be finding similar winds on Jool? If so, I guess it would make the idea of using a parachute somewhat more difficult fun. If we have turbulent winds (meaning varying pressures), do you think there may be places where the pressures and temperatures of the gas coincide in a way that allows for bands/belts of liquid to exist? This would probably be excruciating to model, but I'd love to find small, floating seas flying around in Jool's atmosphere, or just thin bands of liquid circling the planet. Either way, my plan for Jool is going to be pretty boring. I'll likely go in for a descent that is as fast and shallow as possible. Or maybe I'll set up an orbit, and gradually lower the orbital radius whilst trying to pick up speed, just to get an idea of the numbers I'm expecting to need when I properly explore the whole system. If I find that winds rip the ship apart, I might send another probe into one of the poles with a parachute; just for a calmer, more smooshy death. I'll send in one of my less favourable Kerbals though. For kicks. Joerim has let me down a few times recently, so err...sorry little guy. I imagine that with gravity that strong, even if you can find a surface, there's no coming up again.
