Onderzoeksraad voor Veiligheid is from an EC130 accident investigation report, which mentions a descend rate in excess of 846ft/min & 20+G at impact, down from the max 4500ft/min. reached during the descend/freefall.
Please check the Graphs in the previous link to the Investigation Report for this Crash.
Vertical Speed at impact was 1800fpm.
And it hit solid ground. Not a Roof which gave way.
Still it is less flatened (cabin has still almost full height) than what we see in this instance.
