On May 31, 1984, at 1334 m.d.t., United Airlines Flight 663, a Boeing 727, struck the localizer antenna 1,074 feet beyond the departure end of runway 35L during takeoff at Stapleton International Airport, Denver, Colorado. The flight was en route to Las Vegas, Nevada, with 98 passengers and 7 crewmembers aboard. The flightcrew said they were not aware that the airplane had struck the antenna. When they were not able to pressurize the airplane after takeoff, the captain decided to return and land at Stapleton. The approach and landing on runway 26L was uneventful. There were no injuries, but the airplane sustained substantial airframe damage when it struck the antenna. The National Transportation Safety Board determines that the probable cause of the accident was an encounter with severe wind shear from microburst activity following the captain's decision to take off under meteorological conditions conducive to severe wind shear.
