Yes, this has happened previously to Hotspots & Roos. Typically (from what I have read here on R/C U, never happened to me) the lower skin has delaminated and airflow in through the wheel well openings has provided the force to tear the skin off.

What happened after the bottom delaminated? Did it peel all of the way off? Did it hang on and the drag caused the crash? How/why did it go in?

Sorry to see this.
