Re: [GPSL] [Fwd: [Ballooning] Helium vs. Hydrogen]
This has all been covered before.
Someplace in the history will be a complete description of what we do.

I'm curious to know other groups experiences with Hydrogen. Please weigh in on the following questions: (Sorry, that was a really poor pun) Are we crazy? Do I, as my wife suggests, just have a death wish? What precautions do you take to reduce the risk of ignition? I realize that you need a certain amount of oxygen to reach ignition, but let's assume there's enough air accidentally in the balloon when you start filling. Anything else?
