I guess we'll keep this short, since Disney Parks officials have confirmed very little information on this subject to the public. That said, a rather disturbing truth stands that around the summer of 1974, a guest concealed a firearm within the park and fired off multiple rounds. The two confirmed gunshots struck both the ballroom wall in the Haunted Mansion, and a snowflake on Adventure Thru Inner Space, respectively. A third hole was found in the Primeval World diorama on the train, and is speculated to have been made by the same culprit.

So can you still see the bullet holes? Not exactly. But next time you ride the Haunted Mansion, when you leave the ballroom scene with dancing ghosts just before entering Madame Leota's room, look out for a spiderweb on the glass in front of you. That was Disney's solution to covering up the incident. Supposedly the pane of glass is so large, that replacing it would mean destroying the roof of the building.
