The debate here seems, for some, to have lost all sense of logic.
Wrong question.
Here's the right question:
If you were thinking of going flying on a day when icky weather was forecast, or continuing flying when it becomes apparent that the weather is worse than forecast, will you have a better chance of staying on the ground, or getting yourself down soonest, and thus surviving, if:
(1) you've had no intstrument training and
know that if you enter IMC you'll die
(2) you did some unofficial training a while back which you aren't entitled to use and haven't kept current but nonetheless think you can probably survive if you carry on into IMC?
(I've only ever read one account of "inadvertant" entry into IMC that I actually believe was inadvertant, which involved haze over water.)
