Kind of a cool picture though. I think we are being managed and it is kind of ticking me off. If wake turbulence could snap off tails, this would have happened quite often over the years of flying history IMO.

>> and I am still convinced that no amount of wake turbulence would cause the Vertical stabilizer to snap off, especially while in flight<< What about the combination of wake turbulence, undetected stress fractures in the stabilizer, or perhaps some inherent weakness in the composite material, or even manufacturing defect?

This morning, CNN featured a guy talking about how composite materials might fail. He said that any of the multiple layers could separate from the adjacent layer. He illustrated this with a pad of paper by inserting his finger between the sheets on the open end of the pad. You can't see this kind of separation on visual inspection because it is within the composite. Apparently this particular plane was patched at one time. Perhaps the patch obscured a greater defect or caused a subsequent defect. He said that you could detect this kind of flaw with xray and other technology. Hopefully, the inspections currently being conducted by AA on the rest of its fleet aren't just visual inspections. Karen
