After this incident and our lawsuit happy public, I don't want them there.

The owners and pilots can enjoy their airplanes without them.

I think we should ban racing cars too. I mean 83 people died in one wreck at LeMans. Speed and power of cars has increased considerably since then yet the tracks are just the same.

Time bomb waiting to happen.....

no offence meant, but your talking serious bullshit here...why should races be closed to public? everone goes there at his own risk...on every official FIA sancioned event you have signs with: "MOTORSPORT CAN BE DANGEROUS, ATTENDANCE AT YOUR OWN RISK" its even shown on your event ticket...same with airshows

safety measurements on todays airshows and motorsport events are at a very high level in the western world, but you cant avoid accidents by 100%... accidents happen and will happen, you only can reduce probabilty of people getting hurt or killed...

but saying these events should be banned generally is totally stupid...

let other have their hobby and passion...if u r afraid of getting hurt dont go there, as simple as that..

That LeMans crash was over 50 years ago. Many changes have been made to the cars and the tracks to make auto racing safer. However, it auto racing had the same safety record over the last 50 years as Reno, it would have been ended by now.

Ahh, no. The tabs are small surfaces on the trailing edge of the elevators and are adjusted by the pilot using the elevator trim wheel in the cockpit.....At least that's how the standard Stang is setup. I have no idea if the trim system in racing A/C is different.

Adjusting the tab down causes the elevator to pitch the nose up etc.

1) Trim tab gets separated while doing quite a bit of airspeed (some say as much as 450 knots). This alone means you get a sudden pitch-up motion due to the sudden absence of any nose down trim to keep the plane going straight at such a high speed.

2) On top of that, the connecting rod/wire between the two tabs is broken and the second trim tab on the other elevator is stuck in nose up trim.

3) As a result of the rapid pitch up, the pilot pulls about 9-10Gs and passes out.

4) Pilot can't regain control in time due to GLOC (G-induced loss of consciousness).

The short report then goes on to mention that a very similar event occurred in these races with another modified mustang back in 1998. In that case the pilot was also subjected to about 10Gs but was far luckier, he just woke up at an altitude of 9000ft and proceeded to recover and land normally.

If the standard P-51 trim system is still in use, then.....

Only one cable controls both left and right elevator trims (using cable drums). Therefore, if one trim tab fails, the other would not stick up or down but would more than likely move back inline with the trailing edge of the elevator. Max up deflection is 10deg with down being 25deg.

Also looks as if 1/3 of the L/H trim tab is still there?
