I have just found a company in pilot's "where to fly" guide of recent called "SeaWings Instruction Services"
They fly a "Lake LA-4-200" @ £190 an hour
Has anyone heard of these people or this craft?
Appratently its based at Headcorn and Medway Marine in Kent.
In response to the above I am going through an experimental stage, I love experiencing different types of flight and aircraft, I do not plan to take it too far!
