I've a lecturer who spend much of his time as a PhD student looking over 'proofs' of FLT and tying to find that one subtle (or sometimes not to subtle) flaw.

There is one in that small collection, above, that claims his 'proof' was "Originally submitted to American Mathematical Society on February 16, 1991. Not rejected – no flaws were found. Not accepted – the referees could not grasp the key concept." However, it strikes me that ii the referees for American Mathematical Society "cannot grasp the key concepts", then he's out of his depth...
