19 HR delay. Ridiculous on the part of SQ.
Really? I don't think so. As parabellum said, it would have taken some time to source a significant number of wheel units, plus time to move the aircraft, plus time to wait for the wheels to cool, plus time to change the wheels, etc, etc. By the time all that was done, the crew had probably run out of duty time to get to SFO, so off to the hotel for min rest before continuing. Not ridiculous at all.
