In terms of the investigations where we've had access to LVVR, there are actually very few. But certainly as part of our investigations, and certainly recent ones, we've identified investigations in the past where it certainly would have helped. In a recently released investigation, we documented 14 occurrences where the operating crew perhaps misunderstood or misapplied some rules leading to inappropriate response to a signal. These we've added into that particular investigation, so definitely in each of those 14, that would have been useful information to have.
