"I remember the 'bang,' hitting the ground, like a car accident, getting in a car accident." Those words came from co-pilot Mike Welborn, one of two San Antonio (TX) police aviators aboard a Schweizer 333 as pilot, Edward A. Ramirez, fought for control of the aircraft -- and for his life. "Come on, auto! Come on, auto!" Welborn yelled to Ramirez, as the aircraft auto-rotated to a hard landing in a grocery store parking lot. Ramirez and Welborn had launched at about 2:30 am CST Thursday from Stinson Airfield, responding to calls for assistance during a police chase. Within less than a minute, the two officers heard a series of bangs and felt an ominous shudder in their flight controls.
