I have continuously struggled to find some since of explanation as to why such a minimum of debris was recovered much less discovered. Other than precious little, historic accidents at sea have yield this limited amount of aftermath. When airplanes make contact with the water, or ships sink, the pattern of debris is normally very large in that most items surrender to the sea reluctantly. In this case, I guess most of you can recall, throwing a flat rock to skip across a pond, only having the air catch it, provide lift, and the rock rolls on it side and enters the water vertically with a kerchunk and barely a splash. Seems like this phonomia fits, only airplanes hardly contact anything with a kerchunk, and subsequently without a large reaction. However, ValuJet in 1969, left very little evidence on the surface where it impacted. Given the debris pattern, or lack thereof, simular thing in this case?
Contrary to BEA, other than high (load) vertical impact, and if wings level, would not lend itself to a rapid sinking.
