My longest actual flying time was 24 hours from Brize Norton in UK to Hong Kong in the early 1970s on a Royal Air Force VC10. This excludes the time spent on three re-fuelling stops in Cyprus, Mazerah and Gan in Maldives. It was also without TV or radio and we had to amuse ourselves with reading, playing cards, drawing, writing, chatting, etc. What a breeze it is now to fly 12.30 hours direct to Hong Kong non stop from UK with an electronic entertainment centre!
The longest distance I’ve flown is UK to Philippines on numerous occasions. I am very well travelled and no longer enjoy long haul flights but it’s a means to an end and I so enjoy going to different countries and experiencing different cultures.
