Ahh okay, so the legal issues...
Hmm, well. I've been doing some research, so far I've found the two main legal issues (if launching from USA or NZ):
1) High kinetic potential of payload
If the payload drops unexpectedly then you have a pretty nasty unguided missile on your hands. Combined with the unpredictable and uncontrollable drift of balloons, this is probably the biggest problem.
2) Recovery of Rocket.
Consequently because of the drift, assuming you launch the rocket correctly, you know have the potential for an even nastier unguided missile
You're also essentially launching the rocket without knowing where it is launching from I.E you have no idea where it is launching from until it launches. This means recovery is seriously hard for a traditional system. A glider approach would probably solve this problem, but adds a layer of complexity that most would not want. Still, time is easier to come by then $100,000+.
Now, as far as I can find this seems to be the best answer:
First, the rocket needs to be a controlled glider. Alright, so how do you control it? http://www.airstrato.com
This place seems like a good place to start. Best solution would most likely be GSM Communication. However that will require a certain level of automation in case of a blind spot or laggy response. But that's a software problem, and the only cost for solving software problems is ultimately red bull and brain strain. Still, that adds complexity.
I'm going to use http://predict.habhub.org/#!/uuid=aff31 ... c682cf1a8a
this thing to calculate the drift.
So assuming this thing is right, the rocket glider launches out at 162km. If the glider can average a glide ratio of 4, starting at 15km, we can glide 75km. So we're 87km out from our launch site. Not great, but that puts us inland. Just.
This is assuming an ascent rate of 5m/s. At 12m/s the drift is only 71km according to my calculator. But let's go with 7m/s. At 7m/s ascent rate we're 120km away from the launch site at launch but well within glide distance.
So that (should) solve problem Number 2. Of course keep in mind I'm just breezing through the overarching ideas, not going too far into the nitty gritty details.
Now, problem number one. Well I think launching from NZ would be the best choice. Cheaper then US, and the density of the country is only 15 per square kilometre on average. Secondly, it is surrounded by a lot of ocean so if it drifts far everyone can just chill because most likely it'll be out in the ocean. Good for the paperwork, bad for us though. This would make things easier legally, but how much I am not sure. I believe that the best thing to do in order to assure the authorities you know what you are doing (and hopefully you do
) is to launch small scale tests first, like they did with the V2. Start with 1/3 scale, then 1/2 scale then full version, The electronics would be able to be carried from experiment to experiment, and if you are creative then maybe some other things too. Launching offshore by 1-2km would be the best thing to do probably, as winds in NZ are most likely to carry the balloon further out, and that'll let the authorities get a few extra hours of sleep at night.
Beyond that, you're still at the mercy of the troubles with launching to space regardless of Rockoon or not. This, as many people have pointed out is most likely the biggest issue, not the rocket itself.
In total, my method is far from perfect and my mostly just cobbled it together just then. But it does raise a good point: Rockoons are complex, but doable. Cheaper even then a ground launch when talking about a space launch. If project time is not important (2-3 years to get to launch day) then Rockoons are probably your best bet. I can imagine that the project, including R&D would be somewhere around $60-90,000. Compared to the several hundreds of thousands the go fast team spent before they flew it sounds much better!
Any thoughts guys? Suggestions? Any are welcomed.

Not all are straight up Rockoons, but many have valuable insights into possible solutions to problems
