> A baby grand piano weighing 1,400 pounds (640 kg) pierced its legs through the roof but was unable to fully break through.
I consider the legs breaking through to be "breaking through the roof."
Then:
> Calling the myth busted, the team loaded another upright piano with enough sand to reach a total weight of 2,600 pounds (1,200 kg), much more than a full-size grand piano, then dropped it from 75 feet (23 m) above the roof. This time, the piano did smash a hole in the roof and landed on the floor.
Since we've been talking about a heavier aircraft, anyway, I hardly think this Mythbusters experiment proves anything here. As much as I enjoy watching the show, it's not a scientific study of how roofs are affected by heavy objects falling on them. There are a variety of factors to consider, including design, materials, condition, etc.
And finally, even if it didn't pierce the roof in any way, when it slid off the roof, it would land on something, damaging or injuring it.
The bottom line is that you don't want aircraft falling on your house.
