WE ALL DID STUPID THINGS as inexperienced pilots
Learnin out of a book only takes you so far. You actually have to do stuff in order to get experience. The STUPID bit only becomes evident following the experience. Remember the saying, "Life is a hard teacher, first comes the exam, then comes the lesson". Or the other, you start with an empty bag of experience and a bag full of luck. The trick is to fill the bag of experience without emptying the bag of luck.
If you ain't done stupid, you ain't done nothin.
