Great little mission and a good video of the entire adventure..
It's amazing how ingenious some people can be, using an over the counter RC plane, Helium weather balloon, and other available gadgets, including the GoPro camera to achieve the kind of feats that were limited to science labs and universities a decade or so ago.
The reasonably priced and rugged GoPro camera has really revolutionised video footage for amateurs undertaking high altitude adventures like this,
Thanks ElReg, for not letting the Scandanavian's little experiment go unnoticed..
