There were small pieces of wreckage found that had separated from the aircraft before impact but that’s it.

Including an engine. The EgyptAir suicide pilot also shut the engines down about the time he began the descent.

I've never heard what the aircraft's attitude was at the time of impact but since the pilot and copilot were struggling for control, I suspect it didn't go in perpendicular.

It doesn’t have to be perpendicular to nosedive in.
