The location is here at Larry Walters former home where the flight originated.

Lawrence Richard Walters, nicknamed "Lawnchair Larry" or the "Lawn Chair Pilot", (April 19, 1949 – October 6, 1993) was an American truck driver who took flight on July 2, 1982, in a homemade airship. Dubbed Inspiration I, the "flying machine" consisted of an ordinary patio chair with 45 helium-filled weather balloons attached to it. Walters rose to an altitude of over 15,000 feet (4,600 m) and floated from his point of origin in San Pedro, California, into controlled airspace near Los Angeles International Airport. His flight was widely reported in many newspapers.
