That initial A320 flight was a demo flight for journalists where the pilot was intentionally pulling stunts like flying very low in front of spectators. Turns out he was flying lower than intended and basically plowed into the forest at the end of the runway. There was a long, still unsolved debate about where the A320 reacted correctly to the pilot's eventual commands to rev the engines and pull up, but ending up needing to do that was definitely not the plane's fault.
