I just spoke to Julie (VERY briefly). They are at the airport in Nairobi and everyone is safe and well. They took several breaks on their long trip back from Kinango to Nairobi. Everyone is anxious to get on the plane and come home!
They are checking-in to fly home and will depart Nairobi at 11:40p local time (about 5 hours from now at 2:40p CST). Nairobi is 9 hours ahead of SA.
They are on schedule to be home tomorrow night at 6:40p.
