Concorde B allowed a Pacific crossing in a technical sense, if you did a technical stop in Anchorage or Honolulu. And then only to Japan, but not to Korea or China.
In the 90s and 2000s you would have had 747s and a340s doing that nonstop without Anchorage or Honolulu, so if anything that would have made concorde B have an even shorter shelf life.
