I don't know if it's brave or foolish to admit this, but I've done it - some years ago now. I was most terribly shocked by my actions and couldn't begin to explain (to myself least of all anyone else) how I could make such a mistake. What Reds Blues Greens says should be right, but I guess sometimes people do things that nobody, including themselves could have predicted. Fortuitously in my case I was flying a type in which it would only have been critical in a single engined climb situation. But I was and still am well aware of the potential implications of what I did. It was a character building experience, but not one I would like to repeat...
