Sky lanterns

Sky lanterns are increasingly being given away as the latest trend for birthdays, parties and other events.

These are aircraft (flying lanterns) which, similar to a hot air balloon, ascend due to the temperature differences (i.e. differences in air weight inside and outside) created by a flame and then descend again independently at non-predetermined locations.

Flying lanterns are powered by soaked paper or cotton fuel. According to the manufacturer, depending on the design, a burn time of 5–25 minutes is possible. Depending on the thermal conditions, a flying lantern can ascend between 200 and 500 meters with a burn time of just 5–7 minutes.

These originally come from Thailand and are offered under the names Flammea, Sky Lanterns, Feelgood Alive Lanterns, Sky Lanterns, Wish Balloons, etc.

According to Section 1 of the Aviation Act (LuftVG) and Section 16 Paragraph 1 No. 5 of the Air Traffic Regulations (LuftVO), these lanterns are subject to aviation law, and their release requires a permit. A request was made to the North Rhine-Westphalia Aviation Authority and the Fire Protection Department regarding the release of the lanterns. Permission was not granted by the Düsseldorf and Cologne District Governments due to the fire hazard posed by the lanterns and the densely populated infrastructure, which poses a significant threat to life and limb, as well as to the property of third parties and users. Due to the prevailing wind direction and strength, lanterns quickly escape the control of the user and, due to their design, can set fire not only to themselves but also to people and property.

Flying such lanterns without permission constitutes an administrative offense punishable by a fine of up to €50,000, unless it is considered a criminal offense under other provisions. The government is authorized to issue this administrative order by Section 29, Paragraph 1 of the Aviation Act (LuftVG). According to this paragraph, the district government is responsible for preventing operational threats to air traffic safety (aircraft operation) as well as for maintaining public safety or order through aviation.
