I have been literally thrown out of thermals and rolled partially inverted by rotor while flying a very light (1-26) ship multiple times in NV . As a previous poster said, not much of a surprise, i think the “death-by-unusual wx condition” scenario is somewhat overblown. If flying on an extremely gusty day or with rotor condx or in monster thermals, a guy needs to factor that into his margins. If he does’nt then he’s setting himself up for an “unexpected” issue where in reality, it should’nt be unexpected at all. As 2g says, its just another part of proper and proactive airmanship.
