FC I guess that you haven't been to Cuba b4. The politics there are oppressive to say the least. There are 10 1/2 mil. Cubans on the island and around 10 mil. want to leave so given that the USA is only 80 miles distant, Castro does have a serious problem and therefore keeps "means of escape" under tight control.
I made a previous post here but it seems it was removed unless I had finger trouble posting.
I have friends in Cuba and I have lived with the people for short periods.
If you want to know anything, PM me.
Myadvice is to keep away from all Cuban flying machines. There is a maintenance issue!
