One Airmiss filed due to passing a glider in cloud in the descent from FL100 OCAS In a twin piston aircraft.
The incident occurred whilst descending in cloud and IMC and the glider passed close enough to see it in cloud so maybe 20 to 30 meters
This happened in the evening about 10 miles south of the Long Mynd and started a discussion here on gliders flying in IMC without a transponder, proper IFR procedures and equipment while powered aircraft on permits or highly kitted home builts are NOT
