Yeah, and up in such thin atmosphere, it makes sense that the two falling components stayed relatively close to one another until atmospheric drag provided a force to separate them based on drag.<div><br></div><div>I'm _really_ interested by this tendency to stabilize during descent. Perhaps my mucking around with exotic statically stable supersonic aerodynamics is a bit excessive- but even a basic finned teardrop shape could provide a nice stable camera platform for a hella cool return video, (Say, Flip HD video of the stabilized dive-bomb from burst altitude to 10k, followed by an arduino-based parachute release?)</div>

Did we stop spinning and oscillating wildly on the descent? It seems likely, considering the images. This suggests we omit all theories for the destabilization that don't explicitly include the balloon.<div>

Correct me if I'm wrong but if the box stabilized out, it would likely do so with the greatest weight towards the back, which would mean the camera, since not much else was nailed down. Since we're shooting with a wide angle, we'll get quite a lot of area in the shot. It would seem to me rather probable that we'd manage to get a shot with our detritus in it.</div>

<div>It does appear as though there is some line or rope attached to the balloon fragment, trailing behind it, that line or rope bridges the fragment to the cloud layer below visually, to make it appear as though they're connected. If you look at the next frame, however, you can see the 'vapor trail' is still there (this time clearly attached the the marine layer below), even after the balloon fragement has fallen well out of frame.</div>

<br></div><div>The reason I concluded it was an aircraft is it has a rather visible vapor trail. I imagine the balloon very well could leave a trail, but not the shard of the balloon.

<div><br></div><div>Do you think the trail could be powder from the interior of the balloon or condensation on the rapidly expanded helium? It would have to be something generated or released rather slowly after the burst, due to the alignment and trail that appears to be just over the clouds.<div>

I think we just got even more remarkably lucky.<br>
<br>
Our best guess for the burst time of the balloon, based on<br>
accelerometer data, is 17:02:05. This picture is time-stamped<br>
17:02:54, however I set the clock on the camera by hand the day<br>
before, and only to the nearest minute. I think we managed to capture<br>
a shard of the balloon flying off into the distance seconds after the<br>
burst.<br>
