terminology such as flying or to the air. the air domain underwater. this is really a first principled approach to look at this without all the cultural baggage that there is been in the past. i spoke with some experts in this area who say that it could be an earth bound enemy or opponent who has some very sophisticated drones, basically that they are putting up in the atmosphere. is that possible? absolutely. we treat this primarily as a domain awareness cap. a matter of national security that we understand what is in our airspace. aviation security that our aircrew no what is in front of them when they are flying around. when you are flying in f-18, what did you see? we still do not know. what we were seeing were objects
they have already. but it definitely suggests that there is something mechanical coming from something man-made. it may not be a person doing it but it certainly can be an object doing it. what happens when they locate this thing? because it s deeper in theory, we don t know where it is, but it s deeper than we can send divers. so, what do you do? how do you help people who might be in that vessel? so, once you ve located it, you use the r of ease that we have out there with active sooners to locate where it is. those rovs would tell the operator back on the surface exactly where they are, and then they would be able to begin a salvage or rescue operation using a crane type apparatus. the navy has one of these, they have flown it to canada, it s getting ready to be loaded onto a ship and moved on to the potential crash site. so, they can use that crane to pull the vehicle up out of the water, the same way we would pull an f-18 fighter that falls
have flown it to canada, it s getting ready to be loaded onto a ship and moved on to the potential crash site. so, they can use that crane to pull the vehicle up out of the water, the same way we would pull an f-18 fighter that falls into the ocean and drops to the bottom. so, you can definitely pull it out with this crane, but you have to locate it pretty precisely first. one of the things we are talking about is the amount of oxygen that is in that vessel. how are those estimates made? and how do we understand because there s a range, obviously, of how long they can survive underwater. yeah, so we have some standard factors that used based on people, how much oxygen the use, and more importantly, how much carbon dioxide they generate, because that s usually the problem, you tend to suffocate due to carbon dioxide poisoning rather than just running out of oxygen. so, you do those numbers, and with five people in the craft and the amount of space that is their, and they do hasn t
something mechanical or something man made. what happens when they locate this thing, because in theory it s deeper than we can send divers, so what do you do? how do you help people? once you ve located it, you d use the rovs we ve got out there with active sonar. those rovs would tell the operator on the surface exactly where they are, and we d be able to begin a salvage or rescue operation using a crane-type apparatus. the navy has one of these. they ve flown it to canada and it s getting ready to move out to the potential crash site. so they use that crane to pull the vehicle up out of the water the same way we pull f-18 fighter that falls into the ocean and then drops to the bottom. so you can definitely pull it out with this crane, but you ve got to locate it pretty
navy it is called, they operate a very deepwater system called curve 21. it can recover large objects from very deep depths. in 2020 this system embarked on a vessel, a multi mission platform, multi mission ship, this system recovered a helicopter from a depth of 19,000 feet. an f-18 last year blew off the deck of an aircraft carrier was recovered from around 10,000 feet. in terms of recovery, once there s a location and positive id, positive identification, then recovery operation begins. you know what, just a real quick question. and i know that we are moving expeditiously, i pray that people were, but many people asked this, too. it took some days in order to get the kind of
