The reason the last couple of pages are all Eurocopter images is because on the trip we did from Johannesburg to Nairobi all eight aircraft were Eurocopter products. 5 x EC-120, 1 x EC-130 B4, 1 x AS-350B3 and 1 AS-350-BA.
If there were other types on the trip then they would have been shot. All images are in alphabetical order and the ones you looked at last were titled "trip" so they would have been at the end.
