i dnt think its an airline 🙁 this belongs to the flying bulls! this is somthing to do with the drink so after a bit of researc i came up with this The DC-6B, built in 1958, is the latest “addition” to the Flying Bulls family. An aircraft that has a special, honourable past, it is somewhat unusual to expect it to have a bright future ahead of it after 40 years. However, it is just because of its history, as well as a number of other remarkable factors, that it is well known in aviation circles all over the world.
The first delivery left the manufacturers in Santa Monica on 22 October 1958, and went to what was at the time the Yugoslavian airline JAT (Jugoslovenski Aerotransport) in Belgrade, where it operated for three years as YU-AFA before being handed over to the Yugoslavian Air Force in 1961. The DC-6B now flew under military serial number 7451, refurbished exclusively and at short notice, as a VIP aircraft for Yugoslavian president Marshall Tito.
Later, during 1975, the aircraft went to the Air Force in Lusaka/Zambia, where it was also used as a special aircraft for President Kenneth Kaunda. At some point, the DC-6B’s operational time came to an end while it was in Zambia, and it was simply parked and forgotten.

It was not until 1992 that Chris Schutte, manager of NCA (Namibia Commercial Aviation – which also operated DC-6A’s) in Windhoek/Namibia, stumbled across the slumbering DC-6B in Zambia. It then became apparent why this aircraft is so important to today’s aviation enthusiasts: this DC-6B, serial number 45563, is the “sister” of the DC-6B, serial number 45564, and the two were the last aircraft in the DC-6 series to be built.

Both were delivered to JAT at about the same time, passed on to the Yugoslav Air Force, and then freighted to Zambia, where they waited patiently for their fates to be decided. Until now, the only difference has been that the “last” aircraft to be built – serial no. 45564 – was not used for the Yugoslav president. It is assumed that these two are the only ones of the type that are still suitable for passenger use today. An additional point of interest is the extraordinarily low number of flying hours: just 11000 for the 45564, and 7000
