That will be Ali Abutaha [I think that's the right spelling].  He came up
with a steady stream of unconventional theories about Challenger for a
little while.  Some of them were taken seriously enough to be investigated
at some length, with negative or inconclusive results.  Others have not
been pursued.  My impression is that there's a general consensus that his
structural-failure theory is not numerically plausible, although NASA *is*
being more cautious about high-altitude windshear these days.
