Sounds like a “high hitch” where the pin was actually sitting on the jaws instead of in the jaws. It’s pretty common in the trucking industry when the driver gets in a hurry and doesn’t closely look at the hitch to be sure there is no gap between the 5th wheel plate and the trailer plate. Doing a tug test is a must, but a visual inspection is just as important. Glad no one was hurt and you had minimal damage.
