	We launched from Breezewood Elementary School‎ at 1:30 pm, the balloon popped at 2:41 pm at 103,764 ft, and touched back down at 3:09 pm. Again, we were exceptionally lucky with the recovery and were able to drive up to within 200 ft of the package.

	The "package" contains two GPS units connected to radio modems that transmit the balloon's location every 30s, various instruments, and still and video cameras. It's all enclosed in super-space-age, soft-sided insulated lunchboxes and secured to pegboard, cushioned for landing with pink insulation foam.~~[http://www.eatmywords.com/\|name ideas]~~		The "package" contains two GPS units connected to radio modems that transmit the balloon's location every 30s, various instruments, and still and video cameras.

	Why no movies in-between? The clouds were very heavy on launch day, and most of the footage is white-out. Something failed in the video camera a few minutes after popping too, so there's no re-entry video.		Why no movies in-between?

			Oh yeah, and for fun all of the raw video is posted up on projects in /home/spaceblimp4, and here is the script I used to make the youtube-compatible videos: [[Media: sb4_editingMovieForYoutube.txt]]

	The accelerometer package flown was the same as last time, with the exception of having half the memory, so there are 50 observations per second. The data are 0-255, with (roughly) 127 being no acceleration. If you graph it, you can clearly see liftoff, popping, and landing. Until we get some time for analysis, the rest is left up to you:		The accelerometer package flown was the same as last time, with the exception of having half the memory, so there are 50 observations per second.
