==Jet- or rocket-assisted take off==
{{Main|JATO}}
Auxiliary rockets and/or [[jet engines]] can help a fully loaded aircraft to take off within the length of the runway. The rockets are usually one-time units that are jettisoned after takeoff. This practice was common in the 1950s and 60s, when the lower levels of thrust from military [[turbojets]] was inadequate for takeoff from shorter runways or with very heavy payloads. It is now seldom used.

Auxiliary jets and rockets have rarely been used on civil aircraft due to the risk of aircraft damage and loss of control if something were to go wrong during their use. Boeing did, however, produce a version of its popular [[Boeing 727]] with JATO primarily for "hot and high" operations out of [[Mexico City]] Airport ([[Mexico City International Airport|MMMX]]) and La Paz, Bolivia. The boosters were located adjacent to the main landing gear at the wing root on each side of the aircraft and only intended to operate as an emergency fallback in the case of an engine failure during takeoff.<ref>{{cite web|url=http://www.tailsthroughtime.com/2010/04/ive-always-had-soft-spot-for-boeing-727.html|title=The Boeing 727 JATO Option|website=www.tailsthroughtime.com|access-date=2016-11-30|archive-url=https://web.archive.org/web/20161201211111/http://www.tailsthroughtime.com/2010/04/ive-always-had-soft-spot-for-boeing-727.html|archive-date=2016-12-01|url-status=dead}}</ref>
