The idea is actually to blow the doors off, and it's really something that should happen to the other car.
There aren't a lot of opportunities for humor in a drag race. It's just not a terribly funny atmosphere. But the following video gave us a chuckle. It shows a seriously built Mustang drag car losing its roof at the beginning of a pass, and it gets some pretty serious air too. The Mustang does get a chance to redeem itself though and in a subsequent pass, it shows that it can crack off a 10-second pass. That is, on passes where the roof stays on.
The video also serves as one more example of how the Foxbody Mustang continues to be underappreciated. The car's lightweight construction means that it's still a good bet for drag racers even today.
