The world’s smallest twin-jet is a proper aeroplane, designed by a professional aeronautical engineer ? and the progenitor of a whole family of very efficient designs.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.

As with any homebuilt aircraft, the existing Cri-Cri planes have often been modified by their builders, departing from the original design to a varying degree, resulting in varying performance. A small number have been fitted with two jet engines and one example of this model, which it was fitted with two PBS VB TJ20A jet engines.
The Cri-Cri features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed tricycle landing gear and twin engines mounted on pylons to the nose of the aircraft in tractor configuration.
The aircraft is made from aluminum sheet glued to Klegecell foam. Its 4.9 m (16.1 ft) span wing employs a Wortmann 21.7% mod airfoil, and has an area of 3.1 m2 (33 sq ft). The aircraft is also capable of aerobatics within the limitations of twin-engined aircraft. The plans-built aircraft was also designed to be easy to store in a garage and tow on a trailer, with assembly and disassembly each taking only five minutes.
