Here's the latest on this fiasco. In addition to sending this warning to Vaughan Fulton, I also sent it to NAPHA in Windhoek to find out what they knew about it. This is their reply:

Dear Sir

The information you sent our office is correct. The only difference is, that nobody really knows when it actually comes into effect. There has been mention of the 01 July. So, I am afraid at this point in time, everyone is hanging on tentative hooks. May I make a suggestion that you re-route your flight that you fly directly into Windhoek, or the other alternative would be to hire a weapon at your point of destination.

I'm afraid at this point in time I can not be of more assistance to you.

Kind regards
Carlin Sobotta
NAPHA Office

My personal opinion is that this is just a temporary fly in the ointment, and will get sorted out. Hang in there guys and girls. (my comment, not NAPHA's)
