Bewl Water near Lamberhurst
Some seven years ago or more, did have a plane come in for several touch and go then a full stop + take off.
Pilot was going to Africa and needed a pass for water landings prior to the trip.
Also did have one come in on a mayday. Was parked up near the sailing club for several weeks. Local people say that the landing was delayed, so that TV crew could film it landing. Was on the BBC South East news.
