I have flown the 340-200 (the least said about that aircraft the better), the -300 and the -600. The -600 seemed what the 340 should have been in the first place. Takeoffs from JNB were a comparative 'non event' in the -600.
I always thought that my airline would have kept its -600's for JNB...but what would I know?
Fond memories of 'long thin' routes and interesting destinations in the -340.
