November 25, 2004, Corona, Calif. / Cessna 411

At 1434 Pacific time, the airplane collided with terrain during the initial climb about one minute after takeoff. The Private pilot and one passenger were fatally injuried; the airplane was destroyed. Visual conditions prevailed. Witnesses observed the airplane taking off on Runway 25. It climbed straight out about one mile before beginning to fishtail slightly. They observed the right wing rotate down about 45 degrees and then the nose of the airplane abruptly pointed down. The airplane maintained a steep downward path until it disappeared behind trees. The witnesses then observed a plume of smoke.
