Don't hit buildings. They're hard and full of people.

I don't know what happened.

But what I do know is even IF something is wrong with your airplane, you don't try to land in the side of a building. You land in the river right next to the building.

Mechanical issue or not... airplanes don't hit buildings. Pilots hit buildings.



PS: if the radio transmission he made just before the crash doesn't say what was wrong...we'll almost certainly never know. Fire. All gone.
