Yes, I'd just like to add that penetration by Russian military aircraft into North American air defence identification zones has certainly increased over the last couple of years, but it's also relatively regular. We expect that this is a bit of a return to pre-COVID levels, so while we've observed this increase in activity, I would just note that these flights occur regularly and are not deemed threatening as Russian military aircraft remain in international airspace and do not enter Canadian or American sovereign airspace. I would also say the vast majority of these engagements have been professional, which is different, I guess, from what we're seeing on the eastern flank.
