A graph with no numbers on the x axis does not do much.
Have you forgotten this image of an honest witness?
No bank over the Annex! Therefore the sharply curved north path is impossible - that idea has to be abandoned.
There is an abundance of witnesses to impact via a straight path so any logical person would accept that the plane did hit. Therefore we can conclude that the plane had enough safety margin to survive the very brief period after it went over its rated speed. Do you honestly believe the plane couldn't accelerate past its rated speed for 15 seconds without breaking up? It is called fatigue failure - it takes time.
