Origin of rocket jumping

An edit earlier today claimed that rocket jumping originated with a glitch in Quake. While plausible, this idea is known to be false as the secret exit on Mt. Erebus, which requires rocket jumping to reach, was put there long before Quake was written. Also, since there is another secret portal in Quake which likewise requires a rocket jump to reach it, is it really a "glitch"? — RobertATfm (talk) 10:37, September 7, 2014 (UTC)
