Not sure, clearly there are some people in the group with experience in that area. Although recently getting FAA clearance for high altitude rockets has gotten much more complicated, but I believe that is more related to engine power (P and above) than altitude.
It may not be such a big deal for a balloon launch. There is a local group (UMN related?) that did a launch from the field last summer, so that may be a good contact as well.
I just changed my signature so I don't have to keep repeating myself.
If you don't volunteer to organize it, there's no guarantee somebody else will. Even if they say "Yeah! I'll get to work on that!" it wasn't their idea so they're just not as invested.
