 FAIR: The scientists of the future should already have had Coles  last message from the airport before they sent him. They played back  Dr. Raillys message "before" she had left it in the chronology of  the movie, so they could also have had from the beginning all  messages that anyone would leave on the secret machine at any time.  However, the scientists explain that the process is very time  consuming ("one word at a time") and that they had only deciphered  Dr. Raillys message a few days ago, so they might not have gotten  Coles message yet.
