I would throw out everything you have got and DON'T LET GO OF THE STICK. The plane's stick free pitch stability is MUCH worse than its stick fixed stability. When you let go, you are a passenger, accepting whatever the upset brings you. Stay active, and aware of what is happening, and you have a chance. Even if Active is just holding the stick in one position. As to exceeding flaps down limit speed, I would rather have the drag and hope that it hangs together than not have the drag and be pretty well assured that it won't. If you have lost sight of the ground, drag is your friend and speed kills.

But, that is just me.

Where does this "let go of the stick" comes from? Never seen it in any glider flight manual. Is there some magical airplane that does right control inputs to get you out of trouble?

I think that the benign spiral is an urban myth when it comes to flying in a convective cloud, or descending through a cloud layer into a rotor.

The only excuse to let go of the controls is that you are busy to bail out.

As I said in another thread, our (BGA-approved) cloud flying course says
to open the brakes and then use your hands and feet to hold rudder and
stick central - exactly the opposite of 'letting go of the stick'.

Mark: Chukar does say that he felt a stall and then the speed increased
rapidly to 160kts.

Interesting read. I wondered what Wolfgang Langweische had the say on the
subject (pages 342-345 in my copy). He's not as prescriptive but I think
his explanation and analysis is better.

Of course the answer is good pre-solo spin training and mandatory annual
spin checks at the start of each season: no spin checks, no fly. If you
or your club does winch launches, add a couple of launch failures to the
spin checks: the CFI can pull the bung himself or arrange for the winch
driver to simulate a power failure at an agreed altitude.

Spin and Cloud Flying training are just too dangerous in the USA. And when IMC or a spin turn out bad, it's a Tragic Accident, not a Tragic Training Gap. The UK is reckless to provide training for these 'eventualities that should not happen' before they happen.

I related the story to my so in law a a lapsed glider instructor and
current
737 driver.
His answer before I really finished was "his pitot froze,dived to try to
regain
airspeed and pulled the wings off "
And of course that makes sense the airframe is cold soaked and the cloud
has
to be wet or it wouldn't be a cloud .

Just wish it had been so obvious to me.

I think this could be the case in a power plane but not a glider. We dont easily get fooled by a frozen pitot thanks to wind noise, especially not an experience pilot like Bob. Also his airspeed was showing over 160 knots before the wings broke off, so I very much doubt this is a case of frozen pitot. This is a simple case of loosing control due to disorientation in the cloud without proper instruments to regain control. Stall, spin turned into spiral, pilot pulls the stick instinctively to slow down which of course only make things worse in spiral, until wings broke off.
