Weather Balloon Question

Launch it in Kansas, 200 miles in any direction is still fields right? And they use wide angle lenses to to exagerate the curvature. 80K is only ~16 miles so they are not in orbit or anything....Put a receiver on it that drops the camera on a chute, do a HALO and retrieve the camera probably within 20-30 miles of where it was launched with its GPS enabled. Heck throw a cell phone in there with an android app that allows tracking. Get it out of the jet stream and its not going anywhere fast.
