I also worked there for 4 years (Swakop and Whk) and arrived there like all my friends "factory fresh" in terms of experience. We didnt have any crashes (there were a couple of close calls though) but our boss kept his fingers on us 24/7 and frequently flew with us just to check things out! I mean, thats how we learn? An we still had great fun! Maintenance in Nam I always thought was very good. Not changing a fuel selector in over 2 hours? Not very wise! Thats basics but I guess his close call was just that last centimeter too close.
