Since he once viewed a dramatic lightning strike on a kite train at a kite festival, inventor Peter Lynn was particularly interested to study the winch house at Lindenberg. Kites there were flown typically with a 1 millimeter (.039 inch) steel line----a magnet for trouble. What the New Zealander learned was that kites were flown 4,000 days between 1905, the opening of the weather observatory, and 1938, the apparent close of everyday kite operations there, to altitudes regularly exceeding 3,000 meters, sometimes as high as 7,000 meters.
