Hei Luftballon
In short
Hei Luftballon is a German term for a hot air balloon. Recent news includes a balloon from Bad Kreuznach causing disruption at Stuttgart Airport.
In plain words
It refers to a large balloon filled with hot air used for flight. These balloons rise because the air inside is warmer than the air outside.
A simple example
A pilot uses a burner to heat the air inside the balloon, causing it to lift off the ground.
Why it matters
Hot air balloons are used for recreation, tourism, and scientific research. They provide a unique way to view landscapes from above.
Easy to mix up
Do not confuse this with a weather balloon, which is used for atmospheric measurements rather than carrying passengers.
