Ok, I'm sure all of you have heard about or even built high altitude balloons. They often travel to about 80,000 - 100,000 feet (about 30 km or so). I was reading about a lot of them lately and I noticed that all designs had a parachute so that when the balloon burst, the payload could safely fall back to earth. Then I wondered, could you possibly put in less helium (as that is the gas commonly used) so that the balloon will not burst? Would it stay buoyant in the air or not? It seems like someone would have tried this to elongate their mission time. Also, how much longer do you think it would stay aloft if it did stay buoyant in the air?
btw, I hope this is the right forum. I'm new here :)
