The recent 777 event, Southwest 1380, and Southwest 3472 all were not uncontained failures as defined by industry and the regulatory authorities. The initial NTSB press releases for 3472 incorrectly used the term "uncontained" (as does Wikipedia), but if you read the subsequent NTSB accident report for 1380 in the section on previous incidents they state the fan blade in the 3472 event did not breach the containment ring or the debris shield that was part of the inlet inner wall structure, and they do not use the term "uncontained" in that later summary of the 3472 event.
