I did have a very tragic loss when I flew an Cessna into a wall. I was in a very sharp turn, and looking at the airplane. I had not realized that I had in fact gained too much speed for the turn, the wing loading must have been to great because the plane went into the wall. Luckily, no one was injured, and there was no explosion of flames, which is a great benefit and one reason why flying paper planes inside the house is safe! My Insurance gent would not cover the loss though, Freakin' Insurance companies!
