{"guid":"import-7069835bfa533f8d68","title":"Flying for free","subtitle":"Exploiting the weather with unpowered aircraft","slug":"25c3-2940-en-flying_for_free","link":"http://events.ccc.de/congress/2008/Fahrplan/events/2940.en.html","description":"Birds, glider pilots, and recently UAVs can exploit a variety of weather effects in order to gain altitude, remain airborne and travel long distances all with no power input – effectively, hacking the atmosphere to fly for free. This talk will explain the aircraft, techniques, meteorology, hardware and software that we use to achieve this. In the process I will show why the sport of gliding may be of interest to hackers, and explain how you too can get involved in this highly rewarding and low-cost form of flying.\n","original_language":"eng","persons":["Martin Ling"],"tags":["25c3"," Science"],"view_count":259,"promoted":false,"date":"2008-12-28T01:00:00.000+01:00","release_date":"2009-02-07T01:00:00.000+01:00","updated_at":"2026-02-19T13:45:09.923+01:00","length":3631,"duration":3631,"thumb_url":"https://static.media.ccc.de/media/congress/2008/25c3-2940-en-flying_for_free.jpg","poster_url":"https://static.media.ccc.de/media/congress/2008/25c3-2940-en-flying_for_free_preview.jpg","timeline_url":"https://static.media.ccc.de/media/congress/2008/import-7069835bfa533f8d68-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/congress/2008/import-7069835bfa533f8d68-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/25c3-2940-en-flying_for_free","url":"https://api.media.ccc.de/public/events/import-7069835bfa533f8d68","conference_title":"25C3: nothing to hide","conference_url":"https://api.media.ccc.de/public/conferences/25c3","related":[{"event_id":709,"event_guid":"import-86dcc5d427d763434f","weight":1},{"event_id":736,"event_guid":"import-93add0c79a0a5e23dd","weight":1},{"event_id":756,"event_guid":"import-61262399b0beda7cb0","weight":1},{"event_id":1259,"event_guid":"import-0bf8f4e066793d6e49","weight":1},{"event_id":1261,"event_guid":"import-f5bec9e3edc05cc493","weight":3},{"event_id":1274,"event_guid":"import-b24e96b14b74162533","weight":1},{"event_id":1280,"event_guid":"import-f72c9dbe24e1516d0b","weight":1},{"event_id":1310,"event_guid":"import-459d6b860d035d66e1","weight":1},{"event_id":1325,"event_guid":"import-57c2428d76aa862a32","weight":2},{"event_id":1331,"event_guid":"import-b6d9b9d565c00a5acb","weight":1},{"event_id":1337,"event_guid":"import-cb980fd24831107395","weight":1},{"event_id":1341,"event_guid":"import-a8f4cba930451edf37","weight":1},{"event_id":1407,"event_guid":"import-aa97ee865d5e945700","weight":1},{"event_id":1503,"event_guid":"import-019cfe6488a1c1abe9","weight":1},{"event_id":1861,"event_guid":"import-61032e70af2c419203","weight":1},{"event_id":1862,"event_guid":"import-79192964e46292d589","weight":1},{"event_id":1864,"event_guid":"import-870d5c5c27cd127163","weight":1},{"event_id":1865,"event_guid":"import-ad947205e22cb846b1","weight":1},{"event_id":2315,"event_guid":"7521d1fd-8b22-4b27-bbcc-12e3695aeca8","weight":1},{"event_id":2448,"event_guid":"49d47154-9156-46e4-8869-89c1a9be94c6","weight":1},{"event_id":2451,"event_guid":"746c83c2-b29b-41e7-be5b-fafdfe923a5a","weight":1},{"event_id":2899,"event_guid":"0c8f0e98-92ee-42ba-aa75-04fc50344904","weight":1},{"event_id":3042,"event_guid":"6f99831e-89d9-4a9f-ab7e-9712d596227d","weight":1},{"event_id":3615,"event_guid":"74783236-46f4-493c-9574-1b27a44847b7","weight":1},{"event_id":3731,"event_guid":"bc638f9f-0370-42f9-b83c-f85cca4ca38d","weight":1},{"event_id":3734,"event_guid":"34ea8f1f-9fad-41aa-8424-e833f10e5e8b","weight":1},{"event_id":6517,"event_guid":"e77ef54a-5dd7-4be1-80c7-42726b273e6f","weight":1}],"recordings":[{"size":463,"length":3631,"mime_type":"audio/ogg","language":"eng","filename":"25c3-2940-en-flying_for_free.ogg","state":"downloaded","folder":"audio_only","high_quality":true,"width":720,"height":576,"updated_at":"2014-05-10T15:26:46.791+02:00","recording_url":"https://cdn.media.ccc.de/congress/2008/audio_only/25c3-2940-en-flying_for_free.ogg","url":"https://api.media.ccc.de/public/recordings/2327","event_url":"https://api.media.ccc.de/public/events/import-7069835bfa533f8d68","conference_url":"https://api.media.ccc.de/public/conferences/25c3"},{"size":463,"length":3631,"mime_type":"video/mp4","language":"eng","filename":"25c3-2940-en-flying_for_free.mp4","state":"downloaded","folder":"video_h264_720x576","high_quality":true,"width":720,"height":576,"updated_at":"2016-01-27T11:03:33.779+01:00","recording_url":"https://cdn.media.ccc.de/congress/2008/video_h264_720x576/25c3-2940-en-flying_for_free.mp4","url":"https://api.media.ccc.de/public/recordings/2326","event_url":"https://api.media.ccc.de/public/events/import-7069835bfa533f8d68","conference_url":"https://api.media.ccc.de/public/conferences/25c3"},{"size":463,"length":3631,"mime_type":"video/webm","language":"eng","filename":"25c3-2940-en-flying_for_free.webm","state":"downloaded","folder":"webm","high_quality":true,"width":720,"height":576,"updated_at":"2016-01-27T11:03:33.809+01:00","recording_url":"https://cdn.media.ccc.de/congress/2008/webm/25c3-2940-en-flying_for_free.webm","url":"https://api.media.ccc.de/public/recordings/2325","event_url":"https://api.media.ccc.de/public/events/import-7069835bfa533f8d68","conference_url":"https://api.media.ccc.de/public/conferences/25c3"}]}
