I also can't see the program so I don't think it is airing in Canada. You are watching the right program & I see from the info below that it is the 4th story in the series - it sounds like they are all on tonight but perhaps not as it is a bit vague. I receive updates on Matthew from his CarePage site and this is what his mom said:
HISTORY CHANNEL MINI-SERIES INCLUDES MATTHEW
Posted 1 day ago
Tomorrow night, WEDNESDAY, MARCH 16, 2011, at 9pm, Matthew's story of his experience of becoming paralyzed as a result of scuba diving will be shown as part of the series "UNDERWATER UNIVERSE." This particular episode is entitled "FATAL PRESSURES," and is the 4th in the series.
Many people, if not most, have no idea that you can become paralyzed or dead as a result of the pressures endured during scuba diving. Although we have not seen the episode, we have been told that it focuses on the scientific principles and explanations surrounding this occurence. Supposedly they will be showing details of just exacly HOW the nitrogen bubbles effect the process of paralysis and death.
We have not seen the script. We have not seen a clip. We truly have no idea of what the final cut will portray. It will be a surprise to us Wednesday night when we view this program for the first time, along with you.
Our prayer, and the REASON we allowed Matthew's story to be reenacted was for the purpose of potentially helping others. Our desire is to raise awareness of the potential dangers for current and future scuba divers. Each year, far too many scuba divers die from pressures similar to what occured to Matthew. He was fortunate, as -- for some unknown reason, the paralysis stopped progressing up the spinal cord at the level of his heart and lung."
***Matthew, his twin brother & his dad are all in the reenactment.***
