Flaps 40
I flew the 737-200/300 for thousands of hours. We rarely made anything but flaps 40 landings without any problems.
On this approach, the captain was flying the HUD and the FO was visual. She was an admitted HUD addict, and didn't look outside enough until it was too late.
Had she pulled back on the yoke a bit when she closed the power, it would have banged on the runway in typical SWAL fashion. Maybe a bit firmer.
They both just quit flying the plane, although the FO was ordered off the controls.
I have never heard of the “Clutching Hand” either.
