I've been reading this thread since the beginning and I think you've done a really great job so far by keeping faith and strenght all this time with the correct attitude but I think that many of the "lucky" guys down in Maun may have spent 2 months or maybe more hanging around the operators and as a user before me said
Thomas Edison once said:
Many of life's failures are people who did not realize how close they were to success when they gave up.
And I think you're pretty close! why not keep trying a bit you never know if one of the new pilots will give up and leave a vacancy! Have yuo tried looking in some other places like Windhoek? Whatever is going to be your decision I wish you good luck!
