Cri-cri is touted as the “world’s smallest twin-engine plane”, and rightfully so — measuring only 16.1 ft wingspan / 12.8 ft length. The Cri-cri has a cruising speed of 92 knots (MC-10) / 100 knots (MC-12) and a range of 750km (MC-10) / 500km (MC-12). Video after the break. Click here to see the jet-powered version.
