Maybe if the writer for the Yahoo! front page were reading this with a Cockney accent, this would be OK:
Hey, bloke, it ain’t an ‘istoric comeback, it’s a historic comeback. Here in the U.S., we pronounce the H in history, historic, and historical, and the correct indefinite article in front of those words is a, not an. If you don’t pronounce the H, then use an before the noun. You’re welcome. It’s been an honor to serve you.
