Up here in the North West (england) we actually have 2 beaches regularly flown into by GA/ML - Pilling Sands and Middleton. Both border Morecombe Bay and both are/were on the map. Pilling is still OK but Middleton now has some restrictions due to the power plant no fly zone but can still be used by landing south of it and taxying up to the cafe. (BMAA have details of this). Also Southport used to have a beach airfield but this seems disused now.
In the early days of flight beaches in the UK were frequently used does anyone have any details/info on were and when ?
