Steering Column problems of the 1996 Ford Mustang

On 4/12/06 I was going westbound toward tacoma, I made a left turn into a highway divide to cross traffic to go to the doctors office. Traffic was heavy because of the time of day. So I decided to make a left hand turn and go another direction. I waited for traffic so I could proceed. I made a left hand turn into traffic and it felt like my car 1996 Mustang, fishtailed (sunny day dry pavement) so I tried to correct it and the steering wheel was locked and the car took off, so I proceeded to step on the brake as hard as I could but it made no difference. The car went approximately two city blocks, it went from my lane to the other right hand lane, we were headed for the light pole and all of a sudden (with the steering still locked) made a sharp left and through me across three lanes of traffic, over the cement divide (airborne) and into another car and he hit another car. On impact the air bags did not deploy. My car was totaled the other two cars that were involved were repaired.
