|Long range flying wasn't exactly uppermost in the minds of the
Caribou's designers. When long overwater flights were necessary, additional fuel
and oil was carried in the cargo compartment. The rubber fuel bladders were filled
with avgas and then pressurized with the deicing pumps. As fuel was burned from the
wing tanks, more could be added by operating the valves shown at the right. This
particular picture was taken somewhere along the route from Cam Ranh Bay to Kadena AFB in
Okinawa (by way of Clark AB in the Philippines).
