What's weird, is the track in the plane appears correct - e.g., lat/long, but the altitude gets "stuck".

Again, yes - it seems to "bounce" around where I am in lat/long. Most of our dives yesterday had some horizontal movements, but most of it was vertical. Only at the very end of the jump do we "track" (a term used for horizontal separation a group will do right before opening) - Some people can gain 60-80mph (horizontal) in a track.

I haven't figured out how yet to view the data in a 3D model (I assumed Google earth would allow it, but haven't figured it out yet).

Could there be some processing conflicts? I don't know how "powerful" either the GPS chip is or the processor is in the Storm...

Anyway, it was a lot of fun. Will keep trying it and posting tracks - but most likely not till next weekend.
