[amsat-bb] Near Space Flight Question

[Dave Marthouse]

Pardon me asking this question as it only relates to amateur satellites 
in a small way as the packages I refer to don't achieve escape velocity.

Over the years I've followed the work being done regarding flying radio 
packages on balloons.

I'm familiar with the scenario of a balloon carrying a package that will 
go to a predetermined altitude, bursting then returning to the ground.

With the advent of the round-the-world experiments with small party 
balloons, how do project organizers keep such equipment in the jet 
stream so that they travel long distances without the equipment going so 
high that the balloon bursts?
