As an aside older British gliders were required to have speed-limiting
airbrakes, so if it all went pear-shaped you could open the airbrakes
and eventually fall out the bottom of the cloud at a reasonable
airspeed. My understanding is that more modern gliders have airbrakes
that only limit the speed in a 45deg dive.

YMMV - Many, including my Cirrus, are 45 degrees.

JAR-22 requires at least 45 degrees for a glider to be certified for
cloud flying. (This is one of the reasons why the Duo is not.)
