The far-right 707 is Korean Airlines. As to the Herald, no idea, but if memory serves, Heralds and Comets and Brittanias always seemed to be parked on remote stands 'way back yonder' in those days and the passengers bussed out to/from them. Strangely the weekly invasions of IL-18's of Tarom and Balkan Bulgarian all seemed to come up towards the terminal and park on the main concourse airbridge (much to the delight of the spotting terrace) ;-)
