Ah me, lovely to see pics of '44s reappearing after all these years.
After TMAC (British Cargo as it became) went bust and Redcoat acquired one of the '44s, I thought the one they got was G-AZML, not G-AZKJ.
Uniquely in the TMAC fleet, 'ML had the no. 6 tank (centre) fitted which gave it an incredible endurance. Carried about another 15000 lbs of fuel IIRC.
Pretty sure 16+ hours was the longest I ever flew it for. But then if my memory has let me down re: which plane had the no. 6 tank, who knows. I haven't got that logbook with me or I'd go and look it up.
