If Matthew's mom is still out there, I hope we can get some answers here. I think that these answers would remove a lot of the speculation and allow a much more accurate assessment of what caused the injury. Admittedly, we may have given her enough already to arrive at some answers and there's no reason she needs to give us all the specifics.
Information that would still be interesting for discussion:
1. How long were they on or around the bottom before dad left?
2. Was dad actively fishing as well, or just hanging and watching his sons play around?
3. What were dad's turn pressure and ascent profile?
4. What were the twins' pressure when dad turned?
5. How often were they checking their pressure levels?
6. How long after dad left did they remain before starting ascent?
7. If there were no gas issues, what was their original ascent plan?
8. While thay have made many dives together, had they been to the Spiegel Grove before?
9. How about other dives at this depth?
10. How many dives had they done since getting the 119s? Any other deep dives?
Answers to these questions would help, but I have to agree with the general consensus of a significant missed deco obligation, I have used AL80's to 130 ft, and even with 28% nitrox ran low on time way before running low on gas, so I really see a failure to plan, or if planned, failure to dive the plan. I just did the Spiegel Grove a week and a half ago, and even with 2 computers, the dive was planned on the tables and we knew the turn time and abided with it. My prayers go out to the family and I will continue to pray for Matthew to make a recovery that allows him to give testimony to our amazing God and the grace of his love for this child of his. Sandie, if you are following this thread, I will bring this up to the other divers at Orland Park CRC and we will all pray for Matthew.
