And on a lighter note a lovely story I heard a few years ago.
An older very high hour bush pilot cut his fuel a bit fine in his little Cessna one day heading to a private country strip out in the wheat belt, the little Cessna coughed sputted and stopped and moments later rumbled to a stop in a wheat paddock.
The old fella wasn't much keen on walking the last few km back to the strip and as many a country person would know there is usually a bit left in the tank it just needs some encouragement, so he rocked the plane while sitting in it and noted the gauges gave a slight hint of movement. Movement means there's hope and he figured if he kept rocking it a bit he might get enough to where it will count. Turns out he was on the money as when he turned the key it fired up, so without wasting a moment he fire walled it and got airborne, it was good while it lasted but just didn't last long and stopped again before he got to 100'.
It did however get him into the next paddock and some 800m closer to where he was going. Not yet ready to admit defeat he repeated the rocking trick and again got airborne but again only to about 100' before it coughed and stopped, still he was now another 800 odd metres closer to the strip. After 3 goes and 3 paddocks he made it to the strip.
You're never beaten till you give up.
