From Wikipedia, the free encyclopedia 

The Colomban Cri-Cri, also spelled Cricri, is the smallest twin-engined manned aircraft in the world, designed in the early 1970s by French aeronautical engineer Michel Colomban.

The name Cri-Cri comes from the nickname of Christine, one of Colomban's daughters.[1][2][3] 'Cri-cri' 'or 'cricri' is also the French term for the sound of a cricket or a cicada, or an informal name for the insects themselves,[4][5] but it is unclear if this double meaning was intended by Colomban himself.
