that what you often see when ca car hits a house - the plane is lighter than most cars. I doubt if that Cessna weighed 2200 pounds at impact. It probably was moving pretty fast (100-130 MPH or so) but all of the fuel is in the wings. The wings broke off on impact and fell to the street below, preventing a big fire in the building.

Even if the wings had stayed on, there wasn't a lot of fuel on board. My Cessna 172 carries at most 42 gallons of fuel at takeoff. That was a 2000 model, so it might've carried as many as 56 gallons at takeoff but it would've burnt some fuel on the trip. Stupid kid.
