The missiles led the way.
Proceeding further through Denis' book, I have meanwhile visited the SAAF homepage where there are lots of interesting informations about old and current weapon systems, and even those which have not made it into SAAF service.
The latter category includes this particular missile type, and since it's such an interesting story, I have of course remembered it and immediately knew which missiles I've seen here.
From there on, it's not too far to the plane type anymore.
Cheers!
Mike
