- The video shows some of the pitch and roll instability out on the course.
The airplane was not flying a smooth line.

- I believe the still images show left aileron, but the airplane
rolling/yawing right.

- The tab lost was the left elevator trim tab, not the left aileron trim
tab.

- Lots of people in the box seats were looking at the airplane as it came
down - they had turned around.

- I believe the FAA will need to recommend increasing the amount of testing
that is done on the aircraft, to include flutter and stability margins.

- Here's a really excellent video which shows what led to the upset in
detail:

I believe a wake turbulence upset caused severe tail flutter that broke the
linkage to the elevator trim tab..  Look at the slow mo.


Matt-

Very good video.

Something caused the 10G pull up. The tab connection could have failed just
before
the pull up and the hinge held it on for awhile until it finally came off.
No airplanes immediately in front. That is not to say there was no residual
turbulence floating around.

A pleasure meeting you at Reno Matt.

Hopefully we'll get to meet again, Paul.  Hopefully in Reno..

One more very interesting video showing the scale of the maneuver that
led to the crash.  (It includes the crash).
