We lived on the sloop of the Tangubanprau north of Bandung. age 13 (1937). We had an original English tennis court. I loved to fly kites. Also to make all kinds of little airplains out of paper. Often the airplanes would take to the air and rose and rose and flew by themself sometimes as long as ten to 15 minutes. The wind striking over Bandung (Preanger valley) Would rise up the mountain slope and caused that feat. The wind touching you, however, would not give that indication. Flying kites in Indonesia means fighting kites. One would fly ones kite far away over a village and then the kite gets attacked by several enemy kites. Very exiting. Complicated manoeuvring and trying to cut the enemies glass coated line with ones own. Good memories. I suddenly remember. We lived on the sloop of the Tangubanprau north of Bandung. age 13 (1937).

Not so with your average jet... Yes, Johan, and the carbon footprint of that sail plane (and of the eagles) is very low.

Not so with your average jet…

He knows about the rising winds and how to use them. Here where I live at the North Carolina coast in USA I always observe with great interest how the eagles and other big birds can just sail de sky, without flying, for hours. Nature has that all figured out. My nephew Harald Boetz, who lives in The Hague Holland, like to sail plane in Germany around the high mountains. He knows about the rising winds and how to use them.
