DR Navigation
In the dim vistas of my memory I can recall doing DR navigation in the Jet Provost (let's face it we had d@@@ all else). However, Danny, by the late 60s we had modernised with a novel invention called the graduated pencil. this worked in exactly the same way as the thumb except we had pre-marked it to the scale (which scale?) of the map we carried. Its immediate usefulness was then dependent on the remaining length of pencil after it had been re-sharpened a few times.
Even on the Mighty Workules I used a fair amount of DR to keep an eye on what the Directional Consultant was up to. It rarely failed to pay dividends in some way.
Keep up the memories. You claim these are fallible but are nevertheless completely fascinating for us sprogs.
