Bit of thread drift...but yup the original BMA seven 0`s were ex Pan Am -321`s the same as the Lloyd International original two ...Pan Am centered a part liason/engineering package around ATEL at STN which supported those original op`s... Yes & while true concerning the aborted ops from Castle Don as it was in those days,it also made sense to be closer to the engineering support...I don`t believe LTN was ever in the equation when it came to the Transatlantic ops as even with STN`s 10,000ft R/W with 186 pax & full fuel load & those old model engines Lloyd could not plan a direct flight to say Toronto on the ABC`s some days but would file technically into Gander & then with a how goes it with the fuel were be able most times to request an en route diversion to the intended destination. This was the case on warm summer day departures to JFK too.(The 321C was the game changer as Lloyd could do STN-LAX direct or certainly LAX-STN direct..
