Is there anything in the area's the Rov go over to suggest the anomaly came from nessie area ?
Yes, two things.
1. If the "tail" extending northward from the anomaly is a skid mark, scar, or furrow dug by the object as it hit the slope at the base of the cliff, it suggests that the object may have been moving in a southerly direction when it hit. I would expect a coral boulder to travel straight down. The current in that area runs southward which could account for a southerly trajectory if the sinking object was partially buoyant (such as wreckage of the airplane's fuselage). Of course, it could also be that the slope in that particular spot slopes off to the southward which could cause any impacting object to skid southward.
2. The area where the possible landing gear debris field appears in the ROV video is on the line you drew between Nessie and the anomaly. As shown in the attached diagrams, it is at a depth where the reef slope moderates between the first and second cliff.
In other words, things appear to be lining up. You can draw a straight line between any two points. Three points? Not so much. We didn't "back into" these three points. We didn't look for something where we wanted something to be. Nessie is where she is. The anomaly is where it is. The landing gear debris in the ROV video is the only feature of interest that Jeff Glickman spotted after reviewing something like 19 hours of video and when he spotted it he had no idea where on the reef the video was taken. But is the sonar anomaly really as good as it looks to us amateurs? Before we get too excited I want to hear from the pros.
