    You would think with all the spying the NSA does that they would know where this plane went.

    Every once in a while, I bring up GOOGLE EARTH, and slowly pan accross Canada & the United States, enjoying the overhead views of forests, plains & towns. Often, I come across an aircraft in flight! And, with all the spy satellites overhead, how is it that this plane cannot have been seen?

    Sigh!
    The area to be searched is about the size of the united states. That’s about 10 million square km. or 10 trillion square meters. If your resolution were say, 1m by 1m then that would be 10 trillion pixels. Multiply by at least 4 to get the number of bytes needed for a complete image That’s 40 terabytes.
    But the area that will enclose an intact 777 is about 60×64square meters (call it 4000 square meters). So that means there are 2.5 billion blocks of area equal to that which could enclose the intact plane. Detection means that you can pick the signal (plane image) from the background, which may be complex, or not.

    But you are not likely to find the entire plane in any random 4000 meter square area, so it is harder.

    And then there are clouds…

    As far as the NSA is concerned, to do SIGINT you need a signal.

    As for satellites, part of the area is over sections of ocean with little strategic importance under normal conditions, so imaging there would be a low priority.

    Baslim, I tip my hat to your evaluation.

    You make it sound like the NSA gets their computers at best buy. They deal with yottabytes (look it up) since they get millions of text, photo, and video a day. They have up to the second satellite imagery and lets not forget the drones that can be easily launched to cover a wide range of areas without having to assemble large search parties. This isn’t 1970. Technology has improved by leaps and bounds.

    I guess every generation has it’s Mary Celeste or D B Cooper.

    We don’t know that NSA has been tasked to look into this. They would more likely be involved in communications. As I said, you need the signal to have SIGINT.

    As for capability and bytes processed, well if you have a pretty good idea of what your signal is (say voice data) or a reasonable expectation some other signal like telemetry data, the processing is made easier. Satellite imaging falls under the purview of the NRO. And it is possible to hide things from the satellites. It is done all the time. And again, we don’t know that they are tasked to look at this.

    Because image processing is two-dimensional (or more if you include intensity and color), the process of looking for the needle in the haystack is increased, especially if you are not sure that what you are looking for will actually look like a needle.

    And after those Chinese satellite images, you’re not likely to have someone come forward with anything that might not be the plane.

    The real stupidity is that folks are convinced technology can solve all problems in an instant. And we know that no computer software ever crashes, nor do our over-burdened with electronics cars.
