Coming back from the AMSAT symposium in Bochum, I detoured to get a probe launched from Idar-Oberstein. Some packages I received en route with the eggbeater antenna.\u00a0 In 6200 meters altitude I lost the probe. There, it came down with 12m\/s indicating that the parachute had not fully opened. I continued on to the landing zone near Langschied. About an hour after landing I arrived and could\u00a0 reacquired\u00a0 the signal:<\/p>\n

The rest was pretty standard. I went to the GPS position and found the probe nearby. The parachute was stuck in the tree tops so I could only recover the probe.<\/p>\n

I continued further south to Stuttgart. Near Viernheimer Kreuz, close to the border of the states of Hessen and Baden-W\u00fcrttemberg,\u00a0 a probe (P0350063) coming also from Idar-Oberstein had gone down 2 days earlier. I drove off the highway and looked a little bit around for it but found only a plastic bag in a field. The battery must have been empty by now and without radio transmission one finds the probe only by luck. As I realized later,\u00a0 another user of www.radiosondy.info, Lobelt, had also looked for the probe on the morning of September 28th and not found a trace. Most likely, it had entangled itself in the high voltage transmission lines. Maybe the operator of the transmission line had already removed it.<\/p>\n
