WellI am sorry my gratuitous remark about the version of 707 involved produced so much debate- i must admit I forgot that QF operated 'normal' 707s as well, I remember the V jet colour scheme-not very colourful compared with later ones. In any event it was a pretty exotic route (i also misplaced Bermuda for Bahamas ) and someone cleared up my uncertainty about getting from MEX most of the way a cross the Pacific from its hot and high location.
And of course Navigators back then , hard work on that sector and on LHR-BDA no doubt.
I wonder what Sr Cruz at BA today would think of a weeks layover in Mauritus ?
