It took this long to make this gif because gifsoup is a pos. It is clear why she didn't identify it as definitely being a helicopter because it has no propeller, therefore was not a helicopter, plane, or missile of any known kind. The only people who would know are ones with top secret clearance. Notice how slow it moves and the lapse of time between when it's hidden and the explosion. It circles the building as Matt Lauer described, leading to the likely conclusion that it really exploded on the east, not southeast side. The shape, size, and slow movement aren't anything like the digi-plane.
