Obama "Didn't Know"

The airplane usually designated as “Air Force One” when Obama is aboard flew over Manhattan, scaring the hell out of New York citizens. This plane does not do ANYTHING without the knowledge of the president. So why does Obama think we will believe him when he says he “found out about it at the same time you did?” As usual, he’s lying out of both sides of his mouth, thinking we don’t notice. He’s rapidly overtaking Bill Clinton in the lying department. Actually, it’s a simple mistake. So why fire a low-level staffer instead of just owning up to it and apologizing. He has no trouble apologizing for things he (we) didn’t do, in foreign countries, so why this? (Just common sense)
