It’s that time of year, when experience pilots familiar with the local area, forget all their training and fly into hills.
It might have happened to me 4 yrs ago, I was passenger, we took off from Staverton and turned East , well clear of cloud, overhead the racecourse at around 800ft.
I said J*** turn North, - why, - we can’t see the ridge!. - oh
So we flew up to the army depot turned right and in the clear.
Orographic I guess, it was a straightforward VFR flight easy landmarks no particular plan.
We could easily have become a statistic that day
