"David Copperfield has performed a levitation illusion in several magic shows since 1992 in which he appears to fly on stage for several minutes, while surrounded by audience members. The flight is notable for its graceful motion and unencumbered appearance. The illusion was included in Copperfield's CBS TV special The Magic of David Copperfield XIV: Flying—Live The Dream (1992), and has been repeated several times during Copperfield's live tours around the world. The method was created by John Gaughan. An essential contribution to make fluid movements was given by his assistant, dancer and choreographer Joanie Spina."
"During the trick, Copperfield flies acrobatically on the stage, performs a backflip in midair, and then has spinning hoops passed around him, supposedly to prove that he is not suspended by wires. He then floats down into an acrylic glass box which has previously been examined by two audience members, and continues to float inside after the box is covered. An assistant walks over the top of the box, and Copperfield walks upside down moving his feet under the assistant's feet. He then selects a female volunteer from his audience and flies with her in a fashion similar to Superman carrying Lois Lane. The illusion sometimes ends with a falcon named Icarus grasping Copperfield by the wrist and flying off stage with him."

Method: US Patent #5,354,238.
"John Gaughan described how the trick works in US Patent #5,354,238. According to the patent, the performer is supported by two fan-shaped arrays of fine wires that remain invisible to the viewing audience. The wires are about 1⁄4 mm thick, and support about 10 kg each; the arrays contain more than enough wires to support the performer's weight. The wire arrays are mounted at the hips, near the human center of mass, to a harness worn under the clothing. This creates a balance point facilitating a wide range of movements while suspended. The wires are attached to a complex computer-controlled rig above the stage that maintains the tension in each wire, and keeps each array of wires perpendicular to the audience's line of sight so that the wires never overlap one another, which might allow the audience to see them.
During the later phases of the performance, two hoops are used simultaneously, which aids the deception as the hoops do not come into contact with the wires. Instead, each ring is brought flush to the wires before being twisted under Copperfield. In the glass box demonstration, the top of the box is threaded between the two sets of wires in a vertical position, before being rotated 90 degrees and lowered into place. The wires remain in place while the performer is in the glass box, passing through crevices between the lid and the sides. Since the box limits movement and he is only able to rotate on one axis, he stays side-on to the front of the audience while in the box. When flying with a volunteer, he holds her in front of him, and she does not come into contact with the set-up."
