To clarify the BOAC 707 situation, the first two P & W JT3D powered 707-336Cs (G-ASZF/G) were ordered in October 1964 as cargo aircraft on the basis that no British equivalent existed and were consequently imported duty free. The third example (G-ATWV) was ordered in July 1966 as a cargo aircraft but was delivered in November 1967 in passenger configuration due to a capacity shortage. This aircraft was also duty free which caused Caledonian and British Eagle to protest as they had had to pay import duty on their 707s. BOAC ordered a further 4 -336Cs, the last as late as October 1970. Although some were used as cargo aircraft, all of the BOAC -320Cs were convertible. In 1969 two 707-336Bs were ordered for the new trans-polar and trans-Siberian routes to Tokyo. These, of course, were pure passenger aircraft. The two 707-320Cs that BOAC acquired "second hand" were G-ATZD, a -365C delivered to British Eagle in 1967 and acquired after Eagle's bankruptcy in 1968 and G-AWHU, a -379C originally ordered by US supplemental Saturn Airways but sold to BOAC before delivery and thus not really second hand as it was delivered to BOAC direct from Seattle.
