The results are presented that were obtained at the Yakutsk array by investigating the time structure of a muon disk in extensive air showers of primary energy in the region E{sub 0} {>=} 5 x 10{sup 16} eV at distances of 250 to 1500 m from the shower core. The measurements were performed with a large muon detector that has an area of 184 m{sup 2} and a detection threshold of E{sub {mu}} {approx_equal} 0.5sec{theta} GeV and which began operating in November 1995. Two components having different muon-disk thicknesses were discovered, and this requires strong modifications in the currently prevalent idea of the development of extensive air showers. The problem of the existence of E{sub 0} {>=} 10{sup 20} eV events is considered.
