Never get tired of watching that video. Jeff Ethell, Barrett Tillman and Walter J. Boyne are my three favorite aviation writers, with Mark Berent being a close 4th. Jeff contributed a lot to the aviation and WW2 history community, you owe it to him and yourselves to either buy some of his books are check them out of the library, they are all excellent. He is particularly good at showing thing from both sides IMO. It was such a shame that he died in a crash, and every time I see this video and he goes over the fuel tank switchology and how a pilot would have to respond so quickly with a failure at low altitude because of it, it makes me reflect on how easy any of us can be killed even doing something we are considered to be expert at. There are worse ways to go though, at least Jeff Ehtell went out doing something he loved and was noted for.
