Drag the square interlocking pieces to their correct places to assemble the full picture. Jigsaw puzzle is a brain game which develops spatial intelligence in all ages.

Men, boys and seniors alike, are mesmerized with flight and all kinds of aircraft. The 56 pictures in the game give a glimpse of human ingenuity in constructing means of air transport: planes (from military jets, fighters and bombers to civilian passenger carriers), choppers and police copters, hot air balloons, motor-less gliders, fission-powered space crafts, surveilance drones (quadrocopters). What boy hasn't at least once dreamt of becoming an airplane or a helicopter pilot? Even a guy who isn't an engineer, technician or programmer secretly wants to own a small remote-controlled quadro-copter or a toy plane when he is 45 :)
