The cause of the crash was unclear, but first indications were that it was apparently due to some type of technical problem - possibly decompression - and not terrorism.

The only piece of the plane that remained intact was the tail section of the jet and debris was strewn in a chasm and surrounding hills. Bits of human flesh, clothing, and luggage were scattered around the wreckage, which also started brush fires around the area.

They would blame Martians before they blame Islam. Tech glich Bull; these aircraft are designed with redundant systems.

True, but it seems to me that the easiest way to decompress an airplane is to blow open a hole on one side of it.

Isn't one of the pilots always required to be on oxyen when above 12,000 feet? I don't see how decompression could have done this.
