I did not make that claim. What I said is that the job is still largely MK I eyeball, which is certainly true in this case. You are the one claiming that we have the capability to locate the crash site within hours.
Please inform us all what systems can provide the kind of surveillance necessary to spot debris on the open ocean. Feel free to use the entire arsenal of the U.S., Malaysia, Vietnam, Thailand, Singapore. Satellites, aircraft, ships, UAS are all at your disposal. Just note where they were stationed, how long it would take them to get on station, and what their loiter time might be. You may take into account that a U.S. destroyer is in route to the scene, but I haven't seen anything that indicates how long it will take for her to steam to the search area.
The NRO knows exactly where the plane went down as it has in other lost aircraft incidents, and in the case of re-entering satellite debris. Very rarely is any of that information released to civil authorities. Release can be authorized if survivors are suspected, which wouldn’t be the case here.
