Yeah, I noticed that the airbox/rollhoop structure appeared to be missing or heavily damaged, but I wasn't able to find a photo of the uncovered car (I thought it was possible the driver's pod could be laying on its side under the tarp).
I have seen some horrendous F1 crashes where the driver has eventually been OK. For that reason I tried to ignore the fact that they had covered his car with a tarp (usually because there is something they don't want photographed or because they are preserving it for an investigation), that ABC was claiming they had zero info on his condition, that Paul Tracy said a team of doctors was working on him and that it would take a long time to recover, that drivers and crew were emotional. I told my wife "he probably didn't make it", but I still kind of expected to hear that he was in critical condition.
I initially thought they should have resumed the race, but the image of Franchitti sitting in his car sobbing has stuck with me. Unfortunately, this is one of those things that seems weridly foreshadowed in hindsight, but I suppose everything once you've learned the outcome. Drivers said the track was too fast, too wide, too crowded, that the potential for serious accidents was high. Wheldon was in the race on a gimmick promotion, stuck at the back behind the slowest cars.
The new Car & Driver has an article that mentions Porsche using front and rear light decals on these kinds of cars. The tail lamps may be decals with holes cut for LEDs.
