Your comments at 3309' on the triple pointer altimeter are so true. Luckily when I had my salutary experience in a T7 at Worksop there was a QFI on board. I believe a number of Canberras went into the Drink at about the 10,000 foot point to the East of Binbrook; perhaps some ex-Binbrook Canberra ppruners could comment. I understand it took a lot of effort for their Airships' to be persuaded there was a much better and safer presentation.
