Flight 2

Pictures of second very successful flight with improved payload.

As expected GPS stopped working at an altutude of 24km because of a known firmware bug, but an automatic mechanism in the flight software rebooted the GPS module which resulted in a fix once the payload descended below 24km. But with the help of pressure sensor, it was possible to calculate max. altitude of 30km. Graph is available here.
Impact into the ground was pretty hard at over 60km/h because the parachute lines tangled (also seen in a video). Still, the payload survived and had no trouble sending GPS position. Landing spot was a farmer's field. Flight duration was 2 hours.
