Ohhh, that book. It struck horror into my heart when I first got my (very tatty ) copy.
I picked up a book called something like.... ‘Astronomy before the telescope.' A wondrous piece of work that leaves the modern navigator awe inspired.
A while back, Scottish radar put me heading towards a danger area. He said turn right ten. I had me spot on ten miles from the edge. I said to my colleague, "I'm sure his screen mask is wrong, get a bearing and DME from xxx VOR." He sat there for a full 30 seconds, then said. "I suppose I'd better get myself one of those protractory things."
I often wished that I could make him disappear, but if I had been thus empowered, I would have sent him to the middle of the north sea--at night–listening to the Stavanger Consul.
