Editing Doc Savage (section)

===Technology===
Lester Dent kept current with the scientific developments of his era. While some of Doc's gadgets were simply science fiction many of his 'futuristic' devices were actual inventions, or ideas engineers were attempting to produce. Futuristic devices described in the series include the [[flying wing]], the [[answering machine]], [[television]], [[automatic transmission]], [[night vision goggles]], electromagnetic [[Railgun|rail guns]], and a hand-held [[automatic weapon]],  known variously as the [[machine pistol]], the supermachine pistol, or the rapid-firer.  A wide range of ammunition types were used for the machine pistols, including incendiary bullets that smash on contact, coating the target with a high-temperature paste-fed fire, high explosive bullets able to uproot trees, ordinary lead bullets, and the sleep-inducing "mercy bullets".{{citation needed|date=May 2017}} Doc also developed an automated typewriter.
