Many Many moons ago, when was just smaller than knee high.............
My father asked me if I wanted to go fly a kite. Why of course !
I remember him tying a thin metal wire alongside the kite string and connected it to his ham radio. I kept asking how high do you want me to go, his response was as high as you want. We were there in an open field for at least 2 hours. I remember my father having a grin cheek to cheek and a long list of contacts he made while I was flying the kite.
I see this every year at Dayton where someone has attached a long wire to a balloon and making contacts all over from the hamfest.
The Dayton Hamfest, May 2002 , we'd seen a few balloons with wireless cameras watching over the crowd. Now that was wild viewing it from inside the arena.
