I knew a chap who used to land on the beaches around the Isle of Wight.
I was well up for this until said chap's friend told me he'd wrecked his Cub doing it
PS This all happened a long time ago when Pontius was a pilot
The nearest I've got to landing on a beach was a low pass along the surf flat out in a Twin Commanche at 50' (the beach was deserted) on one of the longer beaches in West Wales. Great fun and legal as well cos the gunnery range was closed
