Mark Smith (c. 1950 – 2011 ) was a pioneer in radio-controlled (R/C) model aviation. The son of Rod Smith, an early inventor of R/C equipment, Mark began building hand-launch gliders in the 6th or 7th grade. In his teens he followed his father's footsteps into R/C gliders. He later went on to designing R/C gliders like his 100-inch-wingspan Windfree[1] along with the 72-inch-wingspan Wanderer which were the best-sellers for decades. In the early 1970s he built radio-controlled seagulls for the 1972 movie Jonathan Livingston Seagull.[2][3][4]
