I know a lot about airplanes, and I had never heard of this airplane...until about 12 hours before the original post in this thread. I was reading Warpaint Series #92 (HU-16 Albatross), when in referring to the Italian use of that type, the book said:
"This sometimes precluded the HU-16A from reaching the many small islands around Italy in rough seas, which had not presented a problem for the elderly Cant z.506".
And I went away saying "Cant Z.506-- what is THAT?"
What are the chances of being a 53-year old airplane lover, and never heard of an airplane until today, didn't know what it was, and had my question answered all in 12 hours?
