This morning when I arrived for my 0900HRS DFW Ambassador Shift, I saw what I believed to be a MD-11 on arrival to 18C. The color scheme was a white body with green block lettering near first third of the aircraft. The tail was primarily white, with a circular green emblem similar to a sun burst or outside of a flower, the center was white with what appeared to be a gold object. Does anyone have any idea what this airline was. The center tail had the third engine similar to the DC-10, but the winglets looked more faired to the back, as compared to what I've seen on AAL's older MD11's. Richard Whitenight DFW
