I went to Cape Town last year and paid a visit to the SAAF museum which is on Ysterplaat (excuse the spelling) air base. There are a few static aircraft including a Vampire and a beautiful Ventura. The exhibits will while away a couple of hours and you get the feeling the curator was chuffed to have interested visitors.
It is a bit of an odd place to go to, I didn’t fancy braving public transport as the surrounding area looked a bit “lively”. Instead I got a cab which was a bit bizarre as the security into the air base looks intimidating until you mention you are going to the museum. I must have looked very unthreatening and very much an aircraft nut!
