A Near Space Photo (and a Leg Lamp)

My friends and I recently launched a weather balloon into near space. Our goal was to send a "Leg Lamp" (from a Christmas Story) to 100,000 feet.
A mechanical failure caused the capsule to become separated from the balloon/parachute. The capsule free fell from 60,000 feet without a parachute and survived! Amazingly, all the equipment inside the capsule was recovered intact. The video shows the details...
On board, we had a Canon SD870 point and shoot (using CHDK in time lapse mode), a GoPro and a GPS tracker. For the time lapse of our setup, I used the Trigger Happy dongle and iphone app set to take a photo every 10 seconds on my Canon D60.
We coordinated through the FAA and gave them data to issue a Notice To Airman (NOTAM). According to FAA regulations, if the balloon is under 6 lbs, you don't need FAA approval but it is not a bad idea. Apparently University of Virginia launches balloons frequently so the regional FAA center was used to it.
A lesson learned was to NOT USE ZIP-TIES (even the heavy duty kind) to attach the capsule to the parachute/balloon. The extreme cold and the unbelievable high winds caused them to fail one at a time until the capsule detached from the parachute. The capsule was a Rubbermaid box about the size of a shoe box that was filled with Styrofoam.
