Denpasar (Ngurah Rai) Airport and that area used to have a lot of kites flying around. More so in the 70's but even now there are a few in the windy weather June/July.
Quite a few were big, say 3 metres and more in length with a huge coloured flat tail that could be 10 metres. It took quite a few men to run with the kite to launch it. To make take off more certain the rope of about one cm would be wrapped round a coconut tree and three men would run with that as well, later the tree would be used to tie the rope.
I remember flying as passenger on a DC3 of Jamrud Airlines to Lombok and the pilot (an American called Jack) had to do some 'exciting' moves of the plane to miss the kite ropes. No idea of the heights.
The kites are still around and will cover the back of a big truck in some cases. Nowadays flown more in the Tohpati area for any kite hobbyists among you.
