XTC, your ignorance shows why we do have to give briefings before a flight. Yes they can sometimes be boring, especially for a WELL KNOWLEDGED person like yourself
Yet not everyone there in the briefing knows there stuff and sometimes need a bit of a jog of memory to kickstart the flight. To that effect I hope I dont fly with you or have to give you any briefings as you would find me.......how would you say it......boring!
