Thanks
What a thorough description of the sonar imaging process and the creation of the images themselves. Thanks auv-ee.
When I first saw the sidescan image, I thought, "where are the remaining tail surfaces?" But, based on what you said, and my experience with radar, I'm not convinced that one should expect to see any tailplane segments in that image. It's tough enough to make out the wings.
I guess we'll have to wait for the Ile de Sein to learn any more, although I'd feel a little more comfortable if BEA would release some more images from the Woods Hole team.
