You'd reckon correctly. It is Locarno. Well done SLB.
We stayed at the Arcadia hotel in Locarno for a night on the way back from Italy. I have never experienced a swimming pool as clean as the one at the hotel. It was fantastic. So much so, that we stopped again the following year on the way to Slovenia, and this time it was the filthiest pool at any hotel we have stayed in, and was such as disappointment.
I've come across a few more holiday airfield images during my sort out of my images over the lockdown.
