From a quick google, rain at the circuit wasn't the issue for the helicopter, it was the conditions at the hospital which were too inclement for the helicopter to land there. Wind maybe being a larger factor?If they win, then will any race ever be run in wet conditions?
To take it to a further extreme, if the teams/organisers/FIA are going to be sued if there is a death or serious injury then what happens to motor racing in general? Surely there must be indemnities in place that restrict the liability in case of accidents like this?
Speed was an issue, didn't they prove that Bianchi hadn't reacted to double yellows and thus his own actions were a direct contribution to the accident? It's not like anyone else went off that corner once the flags were waved, therefore why was it just him that came off the circuit once the warning was out that there was a danger there?
The lap Sutil went off, Bianchi was right behind and you can see that he has to correct as the car runs over a stream across the track. It was the same stream that took him off the lap after, and from memory he was still doing something like 130mph when he came off. That's not the "slow and be prepared to stop" required under double yellows in the dry, never mind the wet. The argument against Marussia could be that the family feel they were applying pressure (directly or indirectly) to Bianchi to push harder than he should under the double yellows. Another angle from a bit of reading suggests Bianchi was on worn intermediate tyres, not the full wets most of the field were on, so that strategy call could be in question.
