I would provide data on a couple scopes I've had that took severe impacts from falls, but I won't because each case is a unique occurence, and with the internet, you report one failure, then suddenly there's a huge failure with that particular item. It's not fair to the manufacturer or model unless that fall was done in a controlled test, and applied equally across all brands and models.
I will tell you this.
One rifle (AR platform) fell about two to three feet, upside down (parallel to the ground) on a hard dirt surface, directly on the elevation turret. No issues, no loss off tracking.
Another rifle (18-lb bolt gun in chassis) propped up against a vertical surface, barrel down, falls to a hard tile floor, impacting the elevation turret. That scope, the zero was knocked off less than 1/2 Mil in both elevation and windage, but still tracked after re-zero.
