Analysis

The plt reported that he began taking off on rwy 31 with an 8 kt x-wind, but after he started rolling, he noticed the wind had changed to 'downwind.' The plane 'seemed to pull hard to the left' & he could not maintan rwy alignment. As the acft apchd the left side of the rwy, he thought he had sufficient speed to fly. The acft departed the rwy & landed in a swamp, about 75 ft off the rwy. The plt noted that he should have aborted the takeoff.
