Spaceblimp 3 went up with two still cameras and a non-functioning video camera. There are tons of neat pics from both. These links get you into the series right before liftoff.

• Camera one: liftoff
• Camera two: liftoff

These are about as far out as we got before the balloon popped:

• Camera one: space!
• Camera two: space!

And then, recovery:

• Camera two: land again

The Dataz! (Telemetry)

• Accelerometer data. Unfortunately, it looks like there was a bug in the code and the second half of the data overwrote the first. Anyway, here it is. It's 100 samples per second, start time unknown, but it looks like it captures the pop, some freefall, and the landing. Media:AccelerometerDumpfile 2010-11-13 18-24-41.csv.gz
