Si, seņor, it is indeed the old flying boat base at Puerto Pollensa, Mallorca:
I can recall staying at the nearby Hotel Illa D'Or and watching those Do24s chugging about in the late 1960s. If the water was calm, they used to have to charge around the bay to stir it up a little before taking off.
A champagne cocktail in 'Bar Katy' cost 1/- back then! Sadly Katy herself passed away about 40 years later.
You have control....
