I don't think they want a repeat of what happened to Bianchi, Massa or Senna under the new ownership.
I personally don't think the halos take anything away from the sport. I've never really been a fan of the way open wheel race cars look anyway, so it hasn't destroyed anything particularly attractive in my point of view. When they purposely slow down the cars to make it safer, I'm not a fan of that but so far during testing records have already been broken by Daniel and Seb, so the cars have speed.
On another note, I think this year is going to be good. A lot of different teams have speed. Mclaren might get their shit figured out, Haas was second quickest in testing yesterday and Toro Rosso isn't far off the mark somehow, even with the Hondas.
I think you have that backwards.. Massa was hit by a spring, flying in air and I believe it injured the right side of his face. The halo would've only had deflected it dead center, which it wasn't.
Senna crashed into a concrete barrier at Tambarello corner at speeds over 185mph I believe... Halo would've been useless.
In Bianchi's case the halo would've probably cracked from the pressure. I believe tho if that halo stayed together the fork truck possibly could've rested on top of it.. Maybe not, but Bianchi could've had a better shot of survival.
What killed Senna was the wheel assembly coming back, hitting him in the head and penetrating his visor. What appeared to have happened was that the right front wheel shot up upon impact and entered the cockpit, striking the right frontal area of his helmet. The violence of the wheel's impact pushed his head back against the headrest, causing fatal skull fractures.
I think he may have made it with this new halo.
If they required it before it probably wouldn't have been remotely as strong. It's designed to hold over 27k lbs. That might have been enough.
Correct after he smashed into concrete wall at 180+.. again from memory I believe he went off the race track into sandpit at about 190.. what should halo have done in this situation!?!?
Nothing
His autopsy showed that he died from head trauma from the wheel assembly impact. Not g-force induced trauma from hitting the wall. And he was doing less 135 when he did hit the wall, as telemetry showed 135 mph when he hit the wall.
On lap 7, the second lap at racing speed, Senna's car left the racing line at the 190 mph Tamburello corner, ran in a straight line off the track and struck an unprotected concrete barrier. Telemetry shows he left the track at 310 km/h (190 mph) and was able to slow the car down by braking, and downshifting twice, to 218 km/h (135 mph) in slightly under 2 seconds before hitting the wall. The car hit the wall at a shallow angle, tearing off the right front wheel and nose cone and spinning to a halt.

I think he's questioning if the halo would've held up to the force of a wheel assembly. Frankly, he might have a point. If you do the math, the kinetic energy in that thing would've been pretty massive at those speeds.
I did some quick digging.
I couldn't find all of the weights but I figured the assembly that hit Senna could be a little over 41kg based on what I could find online. Assuming the tire lost zero energy bouncing off the wall and the tire had no give in it, it would be less than 23% of what the halo is capable of withstanding. 26kn vs 116kn that the halo can take. I'm confident he would have survived that, even with the inflated impact energy.
I was also curious about Bianchi, Hissman may be right. Just by the math it doesn't appear that the halo would have saved him but it does look like the nose hits the inside tire first, which could have taken a significant amount of the force and potentially the halo could have deflected the car or at least lessened the injury. He was in a coma for a long ass time so maybe it would have been enough to save him.
We will never know until there is another situation like that.

Interesting. Thanks for doing the math. I figured the v^2 would've demolished the halo. But I didn't realize how much it was designed to take.
The Cat fork loader that Bianchi ran under is a Cat 910M. We have a couple of these on some of our operations that we use to load beams onto Highwall underground mining equipment. The operating weight is just under 18,000lbs. I am not exactly sure how fast he was going, but with the speed, and weight of that piece of equipment, I am not sure that the Halo would have prevented his death. You can see when he runs under it, the whole back end of the loader lifts off of the ground. That is a huge amount of force.
It is a lot.
I think if the car ran the exact same way into the loader then the outcome would have been similar. The only way I see him coming out alive is if the halo didn't allow the car to go under the loader and pushed it off to the side. Then I could see it.
It's all speculation though, I'd prefer to never have to see that happen again.
Yeah, not exactly the scenario under which you'd like to see the logo of the company you work for.
