Bingofuel, that has to be the apocryphal story about the Shackleton crew on a long and dreary patrol far out over the Atlantic in the 1950s, who espied a US Navy carrier through a small gap in the clouds. Quick bit of plotting by the nav and they emerged from the cloud nicely lined up with the deck, gear and flaps dangling... Brand new jets over the side to make space for the "emergency", horrified and embarrassed Shack disappeared as rapidly as possible back into the clag.
Regarding the Porteous Approach, is that confusion with the Porteous Loop with which featured a flick roll at the top, better known these days as an avalanche?
