The name "Grasshopper" was given to the [[Aeronca L-3]] and [[Piper L-4]] light aircraft, both used for [[reconnaissance]] and other support duties in [[World War II]]. The name is said to have originated when Major General [[Innis P. Swift]] saw a Piper making a rough landing and remarked that it looked like a grasshopper for its bouncing progress.<ref name="www.museumofflight.org aeronca-l-3b-o-58b-grasshopper"/><ref>{{cite web |title=L-4 Grasshopper |url=http://ww2db.com/aircraft_spec.php?aircraft_model_id=140 |author=Chen, C.

[[Grasshopper beam engine]]s were [[beam engine]]s pivoted at one end, the long horizontal arm resembling the hind leg of a grasshopper. The type was patented by William Freemantle in 1803.<ref>{{cite book |title=The Beam Engine |last=Crowley |first=T.E. |year=1982 |publisher=Senecio |isbn=0-906831-02-4 |pages=95–96}}</ref><ref>{{cite web |title=Grasshopper Beam Engine |url=http://www.animatedengines.com/grasshopper.html |publisher=Animated Engines |access-date=11 December 2016 |url-status=live |archive-url=https://web.archive.org/web/20161210091100/http://www.animatedengines.com/grasshopper.html |archive-date=10 December 2016 }}</ref><ref>{{cite book|author=Dickinson, H.W. |title=A short history of the steam engine |url=https://books.google.com/books?id=qQU6AAAAIAAJ&pg=PA108|year=1939 |publisher=Cambridge University Press |page=108}}</ref>
