The first heavier-than-air machine to carry a human on a free, untethered flight was a triplane glider constructed by George Cayley and flown in 1848. It was modern in form, having three stacked wings above the fuselage and a separate stabilising tail with both fin and tailplane. The wings were of typical Cayley kite-like planform having a low aspect ratio. The craft was not large enough to carry an adult so a local boy was chosen as the passenger, but his name is not known.
