Dream on.... Captain's call to reject or continue and giving another speed to call out is like giving the lawyers another noose to hang us on. I highly doubt it would have saved the Kentucky crew....doing a high speed reject is a dicey thing at best. You've got numerous variables to account for and keep in mind that they thought that they were on the proper runway..... my first reaction given your scenario is to look for a problem in the aircraft....after all, I am on the proper runway right???
