DJI Phantom
The DJI Phantom series launched in 2013 as an entry-level, GPS-stabilised quadcopter. It pioneered the consumer aerial photography drone form factor. It was DJI’s first fully assembled drone. It was priced at $629. It achieved 15 minutes of flight time. It supported optional GoPro mounting. It used a GPS-enabled NAZA-M autopilot. The Phantom 2 Vision introduced the first built-in camera in the series. The line was discontinued after the Phantom 4.

Airplane
The Wright brothers solved the flying problem by inventing a three-axis control system—not an engine or airframe—but their patent, glider, and first flight all hinge on one insight: without reliable pilot control, powered flight is impossible.

Helicopter rotor
The articulated rotor solved dissymmetry of lift in autogyros using mechanical hinges—not powered rotation. It enabled stable forward flight and jump take-off, but did not enable hovering or VTOL. Its influence on helicopters is real but indirect: it provided the hinge architecture, not the propulsion model.

Jet engine
The jet engine solved thrust scaling for high-speed flight, but Whittle’s and von Ohain’s first implementations were experimental dead ends — low-efficiency, non-production designs that proved the principle but not the path.
