The target thrust reverser uses a pair of [[hydraulic]]ally operated ''bucket'' or ''clamshell'' type doors to reverse the hot gas stream.<ref name="Airplane handbook2011"/> For forward thrust, these doors form the propelling nozzle of the engine. In the original implementation of this system on the [[Boeing 707]],<ref>[https://books.google.com/books?id=zSADAAAAMBAJ&pg=-PA24 "Boeing's Jet Stratoliner."] {{Webarchive|url=https://web.archive.org/web/20240908042237/https://books.google.com/books?id=zSADAAAAMBAJ&pg=-PA24#v=onepage&q&f=false |date=2024-09-08 }} ''Popular Science'', July 1954, p. 24.</ref> and still common today, two reverser buckets were hinged so when deployed they block the rearward flow of the exhaust and redirect it with a forward component. This type of reverser is visible at the rear of the engine during deployment.<ref name=Purdue />
