Yes. As I explained earlier, if people have English as their mother tongue but are fluent enough in French to work at VIA, it may happen that in carrying out these duties in a crisis and panic situation, they may not necessarily comply with the requirement to use both languages. The emergency was to complete certain tasks. That is my assumption, but I wasn't there.
I myself have experienced these types of situations on trains, during derailments, for instance. I can tell you that we focus on the task at hand. Ms. Sirsly used the expression task-oriented, and that is accurate. In these cases, we must proceed to evacuation. Unfortunately, some obligations are probably set aside, but we are attempting to rectify things through training and feedback.
