In 1970 a new German holiday charter airline Calair, was to take over a total of five of the thirteen Boeing 720-025's offered by Jet Aviation and Boeing from the stock of Eastern Air Lines. Most of the time, however, the machines were left in the maintenance area of Jet Aviation at Basle and were rarely used.
Then there was a most dubious deal in 1973 to sell these to Rhodesia and 3 of the 720's eventually ended up there under a shroud of secrecy on the evening of 14 April 1973
Air Rhodesia just adopted Calair's blue stripe livery and blue tail stripes and this stuck, which saw the Viscounts and later the first 707-330B's were painted up in it.
Air Rhodesia (RH) got its Jet career somewhat obscurely in 1973 with the purchase of the ex-Calair Boeing 720-025s,
acquired through Jet Aviation, circumventing the Rhodesia embargo. The worldwide embargo was imposed because the Prime Minister
Ian Smith unilaterally declared independence from Britain in the 1960s, which did not amuse HM's Govt.
The blue livery was simply a slightly modified Calair livery.
Calair called their 720 Boeing 707-720, which even corresponded to the original type designation.
D-ACIP which became VP-YNL carried the more modest inscription "Boeing 720".
