Wardair did operate from LBA direct to YYZ (also from BHX which was interesting to say the least!).
If 14 was in use at LBA the 747 had a landing distance of 5900ft!
At BHX I once saw the plane rotate on the threshold (only short displacement available ahead) - what that must have looked like from the flightdeck I can only imagine.
In Nov 1976 Aviaco brought a DC9-30, EC CTS almost brand new, into LBA landing 33. This when the runway was 5400 feet, don't know what the LDA/TODA's were. BHX divert, LBA was above the inversion fog.
Went out again off 33 direct to Las Palmas with 56 on board. Rotated beyond the 10/28 intersection v near the 15 threshold.
