My favorite piano-moving disaster story is East Coast US in origin.
It comes from one of those specialist moving companies who can charge
frightening fees because they are so serious about moving pianos.

Said company was hired by a widow who wanted a piano moved into her home. And this prospective client
told them HER horror story,
about the last time a piano needed moving.

Her husband had hired the movers, whoever they were.
Moving the piano into their residence
entailed getting the piano up at least one steep flight of stairs.
The landing at the bottom of that flight of stairs
ended in an outside wall.

When those movers lost their grip on the piano,
it went whooshing down the stairs,
hit the wall,
crashed through the wall,
and fell to the pavement below,
in front of the building.
Where the piano finished exploding into matchsticks,
something it had begun to do when it crashed through the wall.

One other detail.
Between the landing at the bottom of the stairs,
and that wall,
stood the lady's husband.
He did not survive the impact of the whooshing piano.
