Who accomplished the first fixed-winged heavier-than-air and powered flight?

The 1903 Wright Brothers flight is officially recognized by the Fédération Aéronautique Internationale (FAI), the standard setting and record-keeping international body for aeronautics and astronautics, as "the first sustained and controlled heavier-than-air powered flight". There is also evidence and witnesses that Richard Pearse successfully flew a homebuilt aeroplane more than 100 metres across a field, over half a year before the Wright Brothers' flight, thus fulfilling the "sustained" and "controlled" requirements; however since he subsequently lost control upon attempting to land and crashed, many do not consider it a valid claim to the record.
