Fox is reporting, Pilot set his own house on fire first, before crashing the plane into the building. That looks like a whole lotta damage and fire for a small plane...
Yeah, post 9/11 some kid stole a small plane and flew it into a building, wrecking only one office. Prior, someone flew a small plane into the White House and pretty much just bounced off. Most people forget airplanes are little more than aluminum balloons. Even 9/11 involved the biggest planes with tanks filled to capacity for long trips, and it was the fire - not the impact - that caused most of the damage.
This thing taking out the entire front (depth of damage unclear) bodes of intent and preparation.
