This a thing that, instinctively, I find it hard to grasp. The capsules are designed with a centre of gravity slightly to the direction of the thermal shield, this assures the right attitude, but how can it remain stable, at such velocities and plasma flow, I find it hard to believe, but it is so!

Reentry vehicles have a turbulent wake, and a transition region exists at some point along the body.

The paper Laminar-Turbulent Transition on Reentry Capsules and Planetary Probes has a good overview.
