The video shows an aircraft that pancaked into a field in a fully stalled, out of control, manner.
These pilots did not maintain their airspeed. They LOST CONTROL of their aircraft.
Before condemning the pilots it might be good to look at this flight path reconstruction:

If we were to assume a loss-of-power event, one likely scenario is that the crew tried to glide towards the airport, but didn't quite make it and had to stretch the final part to avoid hitting the N200 road which runs straight across the flight path just before the eventual touchdown. The consequence of that stretching would then be loss of airspeed and stall or partial stall.
So in this scenario the crew had the unenviable choice between hitting the traffic on the road or lose flying speed.
I have not yet noticed any witness from those undoubtedly numerous who were driving along the N200, who could say how low the plane was when it crossed the road. Tomorrow we will without doubt be wiser on this issue.
