I just want to mention with respect to this that the one proposed by government is much broader than the three others because it says “to cover all persons working in activities that may have an impact on safety, including possibly limiting the number of hours.” So it's not only for air traffic controllers, it's not only for flight crew members, it's for everybody. So I think it's the best of worlds for everybody because it's broader.
