abstract:The Swing Wing is a toy, similar to the Hula Hoop, worn on the head and twirled by moving the neck and/or body in a back and forth motion. It was developed by Transogram Games and introduced in 1965.
The B-1B has a "variable-geometry" or swing-wing design: The wings are swept forwards, almost at right angles to the body, for take-off and landing and cruising.
