Would YOU consider something that happened yesterday as historical?
Likewise, would consider something historical that happens (less often) but often enough that every one hundred years or so that it occurs on a more or less regular basis?
The bombing of the twin towers WAS historical simply because of their status of being the largest towers in the “Known” world and it was done by airplanes which both facts can not be found any place in history due to the overall uniqueness of both the buildings and how they were destroyed.
NOW - THAT WAS HISTORICAL.
