The next machine, Chanute’s design of a soaring machine, was the Katydid , a multi-plane glider. It was re-rigged six times; each new experiment preceded by releasing bits of feather-down in front of the machine and watching the path of air currents sweeping past the wings. The most successful wing variation used five sets of wings in the front and one as tail.
