just to bring us up to a higher state of readiness. hms defender has just left the port of odessa, and as you can see just over there, we're already being shadowed by a russian warship. i have two suspect aircraft coming in. they're soon tracking russian military aircraft who are also tracking them. it is a slightly more increased threat, i'd say, just because we're operating outside of our normal areas. and you're being watched by the russians. they can see us. we can see them. as we get close to crimea, the tension rises. hms defender is going to sail within what russia now claims is its territorial waters, but following a legally recognised shipping lane. would you say there's a flashpoint potentially here, in terms of how the russians will behave? there's a contentious point. their posture will likely be more belligerent because of our proximity to what they recognise as their waters.
