Centaurus,
I love your thought provoking posts. Always interesting and informative. One of the better reasons for reading PPRUNE. Like the back pages of "Flight" magazine used to be, should be a necessary read for all young pilots.
This one brings to mind that wonderful episode of "i learned about flying from that" published in Flying magazine about the C-124 Globemaster caught out in fog over Germany.
Cue: someone smarter than me who can find the link to it and repost it here. It has been posted and discussed on PPRUNE before.
Raises your pulse rate just reading it.
BSD.
