Thanks for the clarification as to the identity of the 52 Sqn aircrew in my photo. The names you mention bring back memories - please check your PMs.
As regards Hans and Lotte Hass. It was only Hans who visited the island in late 1957 and early 1958 as Lotte was at home in Vienna about to give birth to their first child together. Below a couple of photos from my album taken at the time.
Hans died at the age of 94 earlier this year. His obituary here:

...and with his glamorous wife Lotte on an earlier occasion, but not at Gan.
