 We are doing the confined space annual extraction exercise today, so what it entails is it kind of simulates either somebody being non-responsive in tank or being stuck inside the fuel tank or For whatever reason they can't get themselves out. They can't self-egress from the fuel tank overall purpose is to Train ourselves and our people how to be able to get that person out of the fuel tank ourselves rather than waiting for first responders to Come and them do it because in a situation like this minutes minutes matter seconds matter really So being able to get that person out of tank and out of that confined space area To a good atmosphere It's very important. We're the yeah, we're the only we're the only unit on base really that would do this exercise Because we are the only ones that actually go into the structure of the aircraft We're the only ones that go into the fuel cells on this aircraft. There's only one on this aircraft That really it allows us to use what we're trying to do self-aid buddy care CPR While we're waiting for first responders to get here because like I said every every minute counts So it's life or death situation if we can use CPR and self-aid buddy care to help our people out Then that's what we got to do
