FEHoppy, yes I do! If this aircraft would have landed with 4000ft/min there wouldn't be anything left except powder! btw 83kts is most probably ground speed. The fact that this aircraft couldn't impact with 4000ft/min is a sign that these transponder data are not correct.
You need to slow down and look at the data mate. This position is about 250 meters north of the resting place of the wreck. The aircraft is still airborne. Now put this into a picture of an aircraft attempting a stall recovery. As it continues the vertical speed reduces but not enough to prevent impact. The actual vs just prior to impact could be rather different.
PS. 4000ft/min is about 20 m/s
