Think what it was like in the days when no light aircraft carried radio - they managed!
PP The fact is nowadays we are spoilt for choice and there is no sensible reason why we should be lost. Radar services, GPS, nav aids.
Years ago they had none of that not even radios and had to work harder. On the flip side we are more likely to fly into controlled airspace and the airspace is more controlled.
But yes there is no sensible reason to get lost today and even if you do there are plenty of ways to un loose yourself.
