Swedish Engineer's RC Plane Gets a Balloon Lift To Space
mask.of.sanity writes "A Swedish engineer has sent his radio controlled airplane to the edge of space using a weather balloon. It reached 33,100 metres before the balloon popped. The trip is captured on film and he has detailed the project in a blog. Amazing stuff."
I wonder how he tested the radio link. That would be the main technical challenge, I would think.

"Where I live helium is ridiculously expensive. So I went with the much cheaper alternative, hydrogen. It’s also more buoyant, about 8% more. Which means a higher burst altitude as you can use less gas."
Bonus points for using hydrogen instead of helium. Hydrogen is not dangerous if handled properly and helium is a scarce resource needed for many medical uses like MRIs.
