When i visited the airport for the last time last year in my PROJECT when i was in high school, The manager told us that the runway is not able to sustain heavy aircraft, only small caravans and ATRs are able to land at that time untill further expansion but i was so surprise that event, it means the PILOT run out fuel, or their flight plan they file indicates that Arusha was their alternate destination? actually its amazing for me?????
