At the end of September I went to a GIS workshop in Cologne for a few days, and as it so happens, P0950597 from De Bilt landed with very good prediction in a suburb of Solingen, the trolleybus stop right across the street. This was worth a try, especially as I always wanted to use the trolleybus in Solingen, so I made my way to Solingen after the workshop. The sonde must have landed either in the gardens, the backyards or on the apartment buildings standing there.

When I arrived there, I first looked on the street, then on the parking lots behind the houses, without success. A local resident who washed his car knew absolutely nothing. Finally I tried door knocking in the house that seemed most likely to me. Only an elderly lady opened the door for me, I explained my concern. “There’s no such thing here”, she said in the best ruhrgebiet dialect. I noticed that I had to catch the train back to Cologne and started the way home unsatisfied. Probably the sonde had come down in the garden plots behind the houses to which I had no access.

My First Sonde

#1 Essen – Breckerfeld

For a few weeks I had been waiting for an Essen sonde to land near Gummersbach. flynamic, which I had infected with my probe fever, was on board within a radius of 40 km. On the first day of the math precourse at my university, in which I participated every year as a tutor, it finally happened, and P2740506 landed in Breckerfeld, a little further than 40 km away. ON-1 lost the signal at over one kilometre altitude, it would either be a forest landing, or the probe would have made it to a meadow in the valley.

During the tutorial a short arrangement with flynamic, who picked me up at the TH around 17:00 o’clock. We drove briefly by my home to pick up the big Yagi, because the Moxon was still relatively new and I wanted to be on the safe side.

After our arrival at the hiking car park the disappointment followed while decoding: The probe had landed a few hundred meters before the meadow in the forest. We went to the landing point. The closer we came, the greater my excitement was. We hit into the forest and had luck: in the high spruce trees the probe dangled in approx. 2 m height and waited to be picked by us. Parachute and balloon remainings were inaccessibly high, and thus we went, highly pleased, with a probe in the luggage under a dreamlike sunset back home.
