Well, I believe it originally started when a flight attendant who called in was questioned as to why the window shades need to be open for take off and why they couldn't use mobile phones on the aircraft. I didn't hear the reply of the flight attendant as I was not listening at the time, but to quote one of them they said he didn't have a clue as to why these things were, so anyway enter John the pilot. Fortunately he didn't make too bigger d!ck of himself and sounded reasonably intelligent thank goodness! Just curious as to who he was or where he was from...
and yes he did kind of answer why mobiles are not allowed to be left on at all times on the aircraft, he just forgot to mention the bit about refueling...
