Heard of two guys going through Africa in their Lear. Upon asking for the latest weather at their destination they were given 10 oktas of cloud at 5000ft. Puzzled the two pilots looked at each other..
"Confirm 10 oktas at 5000ft?"
"Affem" said the controller. "Yesterday it was 8 oktas but today..eh..its much worse, it is now 10 oktas."
You gotta love it.....
