All Gliders and Early Unpowered Aircraft

The first heavier than air machines that flew without an engine, built by pioneers who learned to balance and steer in the air by gliding before powered flight was possible. An entry belongs here when the cited article calls the aircraft a glider, hang glider or early unpowered flying machine. It excludes powered pioneer era aeroplanes and First World War aircraft. Entries are placed by what their own cited article says, so each one sits in the narrowest group its source supports, and the group page lists it beside the other members.
