WHBM, I remember those days from when I was with IAS Cargo. We (three) travelled on a TIA DC8 63 from Gatwick to Minneapolis among a full load of American passengers. Then we flew up to Winnipeg and then took a DC8, which had come from Gatwick via Dublin, full of race horses (stallions) to Honolulu a couple of days later. Then the next crew flew them to New Zealand. Happy, knackering days!
