* See [http://www.navweaps.com/index_tech/tech-031.htm this] article. It was and to a lesser degree still is possible to move a whole strike fleet very close to the target if it doesn't give away itself. By the same token, planes may be run into an ambush where the first sign of a missile ship they see is a radar suddenly locking them from below. |

* In the Sixties the CIA realised they needed a stealth helicopter for infiltrating countries like North Korea. Although realising a completely silent helicopter was impractical, they took a standard Huey and worked on reducing the noise signature of each component—modifications included replacing analogue components with early electronics and adding an extra rotorblade. Eventually they came up with an aircraft that when flown at a particular speed, along with nap-of-the-earth flying, was unlikely to be detected unless you were specifically listening for it. |

* During [[World War II]], the Soviet Union organized "night bomber" regiments. In addition to flying when they'd be hard to see, they often switched their engines to idle and ''glided'' in over their targets, so the only sound of their approach was air hissing over their wings and fuselages. One such regiment had all-female flight crews, and the Germans they were attacking called them ''Nachthexen'' -- Night Witches. |
