Most of the Namibian sites have self launchers that are shipped down in containers. No towplanes there. Most South African sites used by visitors have tow planes - but many gliders in SA also come down by container without trailers. Usually these are turbo sustainer types - though there is an occasional self launcher. Local SA gliders are usually pure gliders except for a few Jonkers gliders that have jet sustainers.

Here is a link to a photo essay I wrote about the containers. It was submitted to Free Flight but was never published. ROY
