I fear this thread will go the same way as the one Antoine started many moons ago on the same topic....
Keeping it neutral.... after a quick read-through, all the damage was forward and through the top, yet they mention that a piece of the sail (fairwater in the text) was found in the area. This is inconsistant with the collision theory proposed unless the standard shadowing protocol specifies performing barrel rolls in close proximity.
Also, they make a big deal about how the initial acoustic event was originally dubbed an explosion, yet later revised. Two thoughts 1) the graph shown appears to have been photoshopped, need to read the original source docs 2) initial data analysis is frequently revised once more detailed analysis is performed.
As in the original thread, I still view this as conspiracy-theory rhetoric. Bashing the USA is oh-so popular these days.
