the Board's earlier decision to approve BOAC's application for an import duty waiver on two new Boeing 707-336Cs as a precedent. Despite being offered a mixed-traffic version of the Super VC10 and acknowledging that aircraft's superior passenger appeal, British Eagle favoured the 707-320C because of its greater payload and range. This made the 707 a more attractive aircraft for the kind of charter operations envisaged. Aden evacuation British Eagle played a part in the British evacuation of Aden in 1967. The 2008 book "From Barren Rocks...to Living Stones" by Jon Magee records how one of its fleet, a Britannia, intended for a run to the Far East was commandeered at short notice as the emergency escalated. Future fleet plans The plan British Eagle developed in early 1966 for its future fleet requirements aimed to have 25 aircraft in service by the end of the decade, envisaging the operation of 15 jet aircraft – including two widebodies — and 10 turboprop planes. The former were to comprise two Boeing 747 freighters, five 707-320Cs for the carriage of both passengers and cargo and eight BAC One-Elevens – the last three of which were to be Quick Change (QC) models that could either be used as passenger or freight carriers. The latter were to consist of 10 Britannias. The end of a number of Ministry of Defence contracts in 1966 saw the airline with surplus aircraft and two Britannias were sold to Air Spain. Inauguration of Heathrow's first domestic jet schedules The simultaneous arrival at Glasgow of BEA's first Comet 4B revenue service and a British Eagle BAC One-Eleven proving flight from Heathrow on 2 May 1966 coincided with the opening of the city's new Abbotsinch Airport. This event was followed by British Eagle's first Heathrow—Glasgow One-Eleven revenue service on 9 May, making it the second British independent airline after BUA to operate scheduled jet services on domestic trunk routes. Although BUA's services preceded BEA's and British Eagle's by four months, this occasion marked the first time jets were used to operate scheduled services on a domestic trunk route from Heathrow. It also marked the first time parallel jet competition was introduced on a UK domestic trunk route, as well as the fourth time such competition was introduced anywhere. British Eagle initially operated its scheduled domestic jet services with a pair of 200 series One-Elevens leased from the Central African Airways, pending delivery
