Cessna 421 Goes Missing While Enroute to Tampa. 5 On Board

Wow, yet another aircraft that has gone missing because of bad weather. My thoughts and prayers are with the families of those aboard. 5 people on board were lost while crossing the Gulf of Mexico. Of of http://flightaware.com/news/article/Ces ... aboard/102
A 1979 Cessna 421 twin-piston with registration number N4467D owned by Q4 Aviation of Carrollton, TX is reported missing while crossing the Gulf of Mexico near Florida in severe weather. Tampa Bay Online (tbo.com) is reporting that there were five people aboard the aircraft.

The aircraft departed Collin County Regional Airport in McKinney, Texas (30 miles Northeast of Dallas) at 10:02am CDT for a 3h53min flight to Tampa International Airport in Western Florida.

The aircraft cruised at 21,000 feet with a ground speed between 220-240kts before beginning a descent at 1:11pm CDT. The aircraft continued to descent until the last radar position was received at 1:47pm.

What is the minimum altitude that a gradual decompression could happen at? Because if it took them over 30 minutes to descend, then that could be the cause of the accident... My prayers are with them and their loved ones.

I would guess something close to 13,000 feet. (I don't know anything about Cessna 421's thats just a guess :D.)

Okay, it looks as though hypoxia(oxygen deprivation) starts to occur at altitudes around 17,000ft, which, considering that the aircraft was at 21,000ft, could be a possible cause.
