I know when the space shuttle blew apart in the high altitude.....parts were found over such a wide distance......if the plane did disintegrate at 35,000, the similar situation would have happened. What would have made it disintegrate however is another issue?....& why nothing seemed to be made known if it were a terrorist situation remains a huge question.....but then again....then made the 911 look like it was a terrorist attack......so it's not easy to know what the reality of the situation is...only those who were on the plane at the time know what happened & no one will probably ever know what exactly happened.....seems to be the way things go any more.
