Again, thank you very much for the question.
Yes, there is some union involvement, but not in the investigation per se. One of the unions, the guild that represents the officers, has provided the officers with legal advice and support, as has the union representing the crews. In fact I went just a couple of weeks ago to meet with the crew with John Gordon, the head of the Public Service Alliance, and with Mike Wing, the head of the component that represents the crew. So there has been significant union support for the crew in the situation.
