WHBM, I remember those mail flights well; I operated many of them as the sole cabin crew member/firefighter on board. Sat in the Penta or Marriott all day, pax'd to EDI on the BD64, ate my Diamond service dinner, sat some more in EDI then returned to LHR, tucked up by 1.15am. Often 4 days on the trot - a cushy number on nite stop money. I always played the boarding music full blast, because those mail bags scared me stiff - especially running to the back to arm the slides! Sounds crazy, but it was all rather eerie. I loved the views on the way down though - it was often so clear, you could see the lights of Tyneside and Dublin at once. It appeared on the roster as 'Nite Freighter'.
