  {| |} the colomban cri-cri (english: the chirp-chirp sound made by a cricket) is the smallest twin-engined manned aircraft in the world, designed in the early 1970s by french aeronautical engineer michel colomban. ==design and development== 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  span wing employs a wortmann 21.7% mod airfoil, has an area of . the aircraft is also capable of aerobatics within the limitations of twin-engined aircraft. ==variants== ;mc-10 cri-cri :model with a cruising speed of 170&nbsp;km/h (92 knots, 105.6 miles per hour) and a range of 750&nbsp;km (466 standard miles, 405 nautical miles). ;mc-12 cri-cri :model with a cruising speed of 185&nbsp;km/h (100 knots, or 114.9 miles per hour) and range of 500&nbsp;km (310.6 standard miles, 270 nautical miles). ;mc-15 cri-cri :model powered by two jpx pul 212  engines.bayerl, robby; martin berkemeier; et al: world directory of leisure aviation 2011-12, page 110. wdla uk, lancaster uk, 2011. issn 1368-485x ==operational use== 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. most versions can climb with one engine inoperative. in june 2010, eads partnered with aero composites saintonge and the greencri-cri association to present an electric powered cri-cri at the green aviation show in le bourget. the modified airframe with composite co
