Do NOT do this, but think about what happens:

Driving along at 60 miles an hour, throw a styrofoam cup out of the window at the same time you throw out, oh, a marble.

Which one is going to continue moving at close to 60 MPH and which one is going to slow down immediately. That piece of foam would go to zero air speed pretty quickly. And when your tail fin hits it. . . .
