There was allegedly a flying school out there somewhere in our big world, that had one of these aircraft that “violently” dropped a wing at the stall and the aircraft was labelled by the boss as not to be used for student stalls and incipient spin entry, however one day, that aircraft was used for such a lesson and one of the flight crew was fatally injured from a spin that wasn’t able to be recovered from.
Be careful out there, I cringe when I hear stories like the one above!
