Here is some information for those wishing to know a bit more of the EC135:

What strikes me is the rotor blades being remarkably intact, along that with the tail boom.
Some here keep referring to the main rotorblades as being carbon fiber, they are not, they are fiber composite materials, there is a difference.
The picture in post "202" of the fire crew carrying the blade shows practically no damage at all, to neither leading edge or trailing edge for that matter.

Also visible in the picture is the tail rotor driveshaft still attached to the fenestron/blades. Whilst the vertical stabilizer/shroud seems to have been destroyed, maybe in the flare? The whole vertical stabilizer assy, is also made of fiberglass composites unlike the tail boom, and is indeed a very light piece.

In a full auto, engines at idle upon landing, how long would it take the rotor head to come to a standstill if the rotor brake was engaged immediately upon landing on an EC135?
