The Skydivers Over Sixty (SOS), the Jumpers Over Seventy (JOS), the Jumpers Over Eighty Society (JOES), and the Jumpers Over Ninety Society (JONS) are affiliated organisations of the Parachutists Over Phorty Society. As the names suggest, they are for the more senior parachutists. Each of the organisations maintains its own members list and organises competitions and record attempts.
