Interesting conclusions made here, interesting that by attempting to change the direction of the aircraft actually hindered the braking and this part:

"Surprise led the ground-test technician to focus on the braking system, so he did not think about reducing the engines' thrust," it adds. Only after the collision with the wall were the throttle levers retarded to the idle position

 I guess things happened so quickly that brakes were applied without thinking that reducing thrust and momentum was a good idea!

 Both seats occupied, surley somone must have thought about killing the power before they hit the wall a wee bit too late then

Just goes to show you that common sense and logic don't always come to the forefront in critical situations, and of course in this event  very little time

was available to  make those decisions.

Luckily no one was killed and injuries were not critical.

Now am I being a little naive here? This is not the first aircraft in the world to go out of control during a ground run and crash into a solid object. Why was the aircraft positioned so that there was a lump of concrete in front of it? It's a small point, but valid.
