Track of the Nov. 7 flight out and return downwind of the volcano Licancabur, and photo. The white areas are not snow (we are at the Tropic of Capricorn!), but either rock salt, gypsum, sometimes borax, or a mixture of everything. We will almost reach the altitude of the top (5,916 m) and continue our journey by tickling all the volcanoes in their convergence area, and all will work. It was not strong but much safer than the rare pure thermals which never allowed us to reach 1,000 m AGL. About the ground, totally unlandable and without any human life, it is better not to look down and just maintain the safe glide path to the nearest airport. For my \u00ab\u00a0legal\u00a0\u00bb pilot, a youngster who just soloed in April with 40 hours, this ride was the flight of his life, especially since I wanted to leave him controls as much as possible.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\u00a0\u00bb3_4,1_4″ _builder_version=\u00a0\u00bb4.4.7″ custom_padding=\u00a0\u00bb||17px|||\u00a0\u00bb][et_pb_column type=\u00a0\u00bb3_4″ _builder_version=\u00a0\u00bb4.4.7″][et_pb_image src=\u00a0\u00bbhttps:\/\/topfly-aero.com\/wp-content\/uploads\/2020\/06\/13-ALTIPLANO-BOLIVIANO.jpg\u00a0\u00bb title_text=\u00a0\u00bbhdr\u00a0\u00bb _builder_version=\u00a0\u00bb4.4.7″][\/et_pb_image][\/et_pb_column][et_pb_column type=\u00a0\u00bb1_4″ _builder_version=\u00a0\u00bb4.4.7″][et_pb_text _builder_version=\u00a0\u00bb4.4.7″ text_font=\u00a0\u00bb||on||||||\u00a0\u00bb text_text_color=\u00a0\u00bb#0c71c3″]<\/p>\n View of the Bolivian Altiplano from approx. 6,000 m at volcano Licancabur.
