Safety fencing

[Mgas]

I’m sure this has been discussed many times before by more intelligent and better informed people than me, but with Tobias’s injury’s and a clip from Poland doing the rounds I’ve been wondering what can be done to stop safety fencing lifting? More and more often a rider or riders have an incident where the bike hits the fencing first and lifts it leaving the rider to go underneath and impacting with whatever is behind. My opinion is that attaching them to the concrete below the shale might make a difference. Possibly eyelets in the concrete to attach to? 
let’s be honest we all like a little off but people being hurt or worse is not what anyone wants to see.

The fence should be partially buried by about a foot, the normal tethering system at top and bottom used and however much of the fence below track level filled with water. The section filled could be totally separate from the airside.

Riders will no doubt still get hurt but airfences lifting or sections separating is a common problem, so my idea may appear daft but if you don't try you don't find out.

Alternatively phase in foam fences as and when air fences reach their replacement date. I cannot recollect any incidents where the foam fence lifted.

No doubt I'll be informed about them sooner rather than later.

The foam fences do seem a lot less forgiving than the air fences though... I've always thought that a solid deformable barrier should be placed in front of the air bags, made from thin aluminium or something
