Salvatore has a Partenavia P64 in which he 'tours' Malta, Pantelleria, Lampedusa, Monastir etc. Dunno re hire, but he took my partner in aerial crime to Pantelleria for nothing while I followed in another aeroplane with the ladies. He's an enthusiast, so I'm sure something could be worked out - just don't press to test on the legalities of 'hire'!
He'll also use the Partenavia to pick you up if you've arrived at Catania by big silver bird.
Other aeroplanes - he had a Piaggio P19 (side by side low wing taildragger) for sale and was looking to buy an Aztec last time I saw him (Nov).
Forgot to mention - the Eremo is silent and therefore idyllic.
