Thanks for the responses guys.
Have been in Luanda for nearly 4 weeks now and have had a good look around the airport especially SONAIR's setup but that was on a different subject.
So far the only piston aircraft I've seen is a fairly tired looking Baron in the back of one of SONAIR's hangars.
CP, don't suppose you recall the area where the meatbombs were? I did loads of jumping and jump flying back in Australia.
Cheers
