NavList:

Speaking of The Riddle of the Sands, just six years, Hewitt Schlereth noted:

There are some more general sources for aiming off, often quite good reading, just as a good read. I'm thinking of Harold Gatty who was Wiley Post's navigator in the Lockeed Vega (?) Winnie Mae. There he details how he made sure he found the re-fuel sites by aiming off so as to always know which way to turn when he reached a known land feature - often a river.

Then there's Erskin Childer's novel The Riddle of the Sands, in which aiming off plays a crucial part."

Just a little NavList nostalgia...
