I cannot believe that an aircraft would fall apart just from sabotage. There are too many bolts and rivets to loosen. The only other instances that could cause a plane to fly apart, that I have seen or read about, are:

- mid-air collision
- explosion of mostly empty fuel tank filled with aerosol vapors, bomb, or rocket
- ground-based laser weapon, SDI (believe it or not)

The point is no technician working alone could loosen enough fasteners to cause the plane to come apart in so many ways, and go unnoticed. And the wing! That's got to be the strongest part of the plane! The only other alternative is if a lot of energy is delivered to the structure as in an explosion. But security is so tight...?!?

In that wreckage there's got to be some hint of what actually happened.
