Talking of maps....I remember flying a Talair Baron alone from Hoskins to Lae in the early 80's, with a nicely folded WAC chart on the right hand seat. (I think it may have been for another "company sponsored" gathering at the Lae Dero Club).
Somewhere approaching Cape Gloucester the edge of the map slipped under the door sill and within seconds my sole means of navigation had disappeared out of the a/c and was wafting it's way down to West New Britain. So with a bit of dead reckoning and driven by a thirsty disposition I navigated my way successfully to a much appreciated beverage.
So who needs a map when driven by primeval instincts??
