I don't believe in "get-home-itis"
Actually, I note this apparently was a business trip. Reading this thread immediately reminded me of an incident report in one of the BEA (Bureau d'Enquêtes et d'Analyses) publications.
Essentially it was some guy trying to get to a meeting by private (light) aircraft, crappy weather en route and at destination, pressed on, got in trouble but luckily lived to tell the story (to the BEA investigators
) -- I think in that case he eventually found a hole in the clouds with ATC assistance and managed to put it down on a field. I've tried searching for the report on line but no luck.
