I remember seeing a Wardair 747 at Birmingham airport sometime in the 80s. The flight continued to another UK airport - it may have been Cardiff before routing back via BHX.
One of the Wardair flights from BHX also picked up/set down at Leeds Bradford. Recollection is that it was YYZ>LBA>BHX>YYZ but it may have involved BHX in both directions. LBA's 7380ft runway with obstructions to 32 climb and density altitude issues at 682 feet elevation made regular direct operations over the pond a bride too far.
