During World War I, the need for fast aerial reconnaissance of a battlefield without presenting the easy target of a dirigible or hot air balloon led a few countries to experiment with man-lifting kites.

One system, developed by Boston kite maker Samuel F. Perkins, used a lead kite to test wind conditions, followed by additional kites to add lift until the string could support the weight of a man.

The brave passenger, perched on a narrow seat, was then raised into the air while a ground crew manipulated winches and ropes to keep the system stable.

The entire concept, which left the passenger vulnerable and subject to plummeting with the caprices of the wind, was of limited use on the battlefield, but made for some entertaining demonstrations on the home front.
