But everything went well, and almost immediately we started receiving telemetry reports from all over the province.

At the University, students were waiting with the precision goniometer to estimate the position of the balloon.

Somebody (!) did something - Murphy? - and the computer processing the data had stopped showing the data.

Graph showing humidity. In reality, it seems that the sensor had been damaged. The data were not very reliable.

Graph of the temperature. By a mistake in the program's calibration the graph left the screen. In reality it went to minus 80C!
Height graph. Same error as above. Maximum height reached was about 29000 meters.

Battery voltage graph. Followed perfectly the predictions made!
Las data received, during the descent. The center column indicates the rapid raise in temperature during the fall.
