Yes, I think that's the accident featured in the TV prog. I seem to remember that reverse thrust reduces directional stability with rear engine airplanes but not with wing mounted engines as on the 738.
Not arming the speedbrake in the before landing checks turned out to be the fatal error caused by too high workload on the approach.
Wonder if any lessons could apply here with the human factors side of it, workload management could be a big factor if plans had to be changed at the last minute.
