This led to the absurd situation for British Airways that as the launch customer for the Boeing 757 to replace the Trident, the brand-new "advanced" aircraft had inferior all weather operations capability compared to the fleet being broken up for scrap. An indication of this philosophical divide is the comment from a senior Boeing vice president that he could not understand why British Airways were so concerned about the Category 3 certification, as there were only at that time two or three suitable runways in North America on which it could be fully used. It was pointed out that British Airways had 12 such runways on its domestic network alone, four of them at its main base at Heathrow.
