OK, everybody appears to be confused on many things. I can't say that I have any answers, but I do have some interesting hypotheses. First, it looks to me now that the Race is going now to Pemba Island, Zanzibar rather than the more obvious (and more travelled) Zanzibar Island, Zanzibar. That makes it quite difficult to get to by air from Dar-Es-Salaam. Here are the choices for Monday Dec. 4:
PW730 departs DAR 0730 arrives ZNZ 0750 B4 601 departs ZNZ 0945 arrives PMA 1020
B4104 departs DAR 1545 arrives ZNZ 1605 B4 603 departs ZNZ 1630 arrives PMA 1700
Now, the alternaitve to get to Pemba is to take surface tranportation from Dar-Es-Salaam to Tanga about 100 miles north, then switch to dhow for the trip across the Zanzibar Channel to Pemba. This is an interesting tradeoff and one that apparently Uchenna/Joyce and Charla/Mirna take (and I would take since they reach DAR early Sunday evening). See if this helps.
