From the plot on Google Earth, the rate of descent and speed are fairly normal for an ILS in a B737 until the point when they are passing the golf course to the east. From that point, the speed is decaying steadily but the vertical speed remains constant until they cross over the motorway, where the vertical speed increases rapidly as the wing stalls. Yes Dani, I said it stalled. For me, this points to a lack of thrust and an attempt to avoid striking the motorway, followed by a loss of control when the stall occurred.
