My late father recalled making this kind of mistake in a Beau in WWII. I have tried to find the story in his book but cannot locate it at short notice.
It was two fields on the North Devonshire coast - I THINK - but don't make suggestions as I cannot recall. Anyhow, when they realised that they were on the wrong field, they just taxied back to the end of the grass strip and hopped the three miles to where they should have been. My father navigating (no electronics or fancy gasometers), was advised by his pilot as to the correct nature of his parentage
Fortunately, it was not an operational flight and no one to notice. The folks at the wrong field just waved cheerily!!
