Note, please: “a historic event,” not “an historic event.” Unless you’re in the habit of saying or writing “an helicopter” you’ve got no cause to say or write “an historic.”
I get what he's saying here. However, my accent tends toward ellision, and speaking I leave out that H, so I do need the "an." Also, I run it together into one word: "anistoric." Because I say it that way I write it that way. It's a Virginia thing.
