many years ago - me & ross took a C152 up and did some mountain and valley flying using clouds as the terrain - probably + 3500 feet - we both had about 150 hrs each
ross was a confident hang glider pilot as well
anyway, i'd be guessing in a tighter turn (ross as PIC) and slower speed (its a memory after 40 years) ............ ye olde C152 fell out of the turn / shook / fluttered / and pointed to the ground
it was a total loss of control if you can say that about a stall - we looked at each other with understanding and continued flying - ignoring more cloud mountain and valley flying - we had unintentinally practised what we had been preached
(at height .............. ignoring staying clear of clouds ............ of course)
