The pilot delayed momentarily to assess the wind conditions before initiating the takeoff. The aircraft climbed to an altitude of 75 feet, at which point it began to lose altitude. The pilot described the sensation as if the airplane was "being pushed down." Corrective measures were applied by the pilot, but the descent could not be arrested. The aircraft subsequently impacted the runway, resulting in substantial damage.
