Rear spoiler causing cars to go airborn?  

I watched this race and saw the crash also. It seemed extremely similar to the one where Edwards car spun and flipped. They are saying it's due to the fact that the wing sticks out beyond the back of the car body and catches too much air when the car turns around at high speed.

I remember seeing cars spin before this large spoiler was added and when the car would start to lift, the roof spoilers would deploy causing it to set back down onto the track. In these two crashes however, the roof spoilers, even though they deployed, weren't enough to overcome the lifting effect of the wing.

They are actually going to modify the cars very soon and have them change back to the old spoiler design. Hopefully, that will prevent this type of accident from happening again.
