The probe would eventually drop a little bit short of Pullach into the Forstenrieder Park at 9:40 AM. At this point in time I was about 120 km away and could not receive the probe.<\/p>\n<p>First I went to Schorn that is south of Forstenrieder Park. Passing by the park on the high way, I could shortly hear the probe with the radio. Good.<\/p>\n<p>In Schorn, I found a spot where I got a reasonably good signal from the probe. Decoding it, I had my GPS fix &#8212; good:<\/p>\n<p><em>&nbsp;[17032] (L4743676) (2018-08-13) Mo 09:15:42.720 lat: 48.03539 lon: 11.45236 alt: 705.7 (d:72.1) vH: 2.1 D: 18.8\u00b0 vV: 3.1 DOP[16,21,29,26,4] 29.4<\/em><\/p>\n<p>Reaching the park was not really easy as it is rather large and not really accessible by car. I drove as close to the probe as I could &#8212; and I still had to hike for about 40 minutes and 4 km. Looking at the fir trees that were about 25 m and more high I became somewhat pessimistic about the possibility to recover it. The forest&nbsp; resembled those I had visited with my grandparents as a child. Same look and same smell. Maybe we had even been in that very park together &#8212; loooong ago. I liked it.<\/p>\n<p>I finally arrive around 12:40 in the landing zone and I quickly located the probe hanging in a tree near the decoded GPS position &#8212; unfortunately in around&nbsp; 20 m height. I had brought a telescope rod with around 8m &#8212; no way to recover the probe. I returned to Stuttgart with nothing but a couple of pictures.<\/p>\n<p><\/p>\n<div class=\"mceTemp\">&nbsp;<\/div>\n<p><figure id=\"attachment_5252\" aria-describedby=\"caption-attachment-5252\" style=\"width: 1850px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_Trajectory.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5252\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_Trajectory.png\" alt=\"\" width=\"1850\" height=\"869\"><\/a><figcaption id=\"caption-attachment-5252\" class=\"wp-caption-text\">Trajectory of Ozone Probe<\/figcaption><\/figure><br>\n<figure id=\"attachment_5251\" aria-describedby=\"caption-attachment-5251\" style=\"width: 1484px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_Reception.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5251\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_Reception.jpg\" alt=\"\" width=\"1484\" height=\"977\"><\/a><figcaption id=\"caption-attachment-5251\" class=\"wp-caption-text\">Bearings (red) and my hike to the probe (blue)<\/figcaption><\/figure><\/p>\n<p><figure id=\"attachment_5249\" aria-describedby=\"caption-attachment-5249\" style=\"width: 4032px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1376.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5249\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1376.jpg\" alt=\"\" width=\"4032\" height=\"3024\"><\/a><figcaption id=\"caption-attachment-5249\" class=\"wp-caption-text\">Landing Zone<\/figcaption><\/figure><br>\n<figure id=\"attachment_5245\" aria-describedby=\"caption-attachment-5245\" style=\"width: 3024px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1345-e1534622614721.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5245\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1345-e1534622614721.jpg\" alt=\"\" width=\"3024\" height=\"4032\"><\/a><figcaption id=\"caption-attachment-5245\" class=\"wp-caption-text\">Landing Zone with Puddle<\/figcaption><\/figure><\/p>\n<div class=\"mceTemp\">&nbsp;<\/div>\n<p><figure id=\"attachment_5248\" aria-describedby=\"caption-attachment-5248\" style=\"width: 3024px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1372-e1534622368602.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5248\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1372-e1534622368602.jpg\" alt=\"\" width=\"3024\" height=\"4032\"><\/a><figcaption id=\"caption-attachment-5248\" class=\"wp-caption-text\">Probe hanging in fir tree<\/figcaption><\/figure><br>\n<figure id=\"attachment_5246\" aria-describedby=\"caption-attachment-5246\" style=\"width: 3024px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1349-e1534622466488.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5246\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2018\/08\/20180813_IMG_1349-e1534622466488.jpg\" alt=\"\" width=\"3024\" height=\"4032\"><\/a><figcaption id=\"caption-attachment-5246\" class=\"wp-caption-text\">Probe dangling in tree &#8212;
