The characters on ABC's FlashForward are getting increasingly tense as the big blackout date (the date almost everyone on the planet saw in a future vision when they blacked out for 2 minutes and 17 seconds) approaches. That date, April 29, just happens to be a Thursday, the same day that the series airs. It all seemed like karma to the producers ... until they realized that the show's April 29 vision date wouldn't quite be able to match up to the real April 29.
