You can't live in an air pocket in a car for an hour. In almost no time at all the air pocket would be your exhalations and not breathable air.Good grief....the truth is that Ted Kennedy was drunk, he drove his car into a lake, he got out and left Mary Jo to DIE. He walked passed dozens of houses on his way back to the party to get his brothers. Mary Jo lived in an air pocket for an hour after the car went into the lake. Had he gone to the first house and called the cops, she would have survived. Then he swam to the mainland and put in an appearance at the hotel bar as an alibi.
The Kennedy family paid Mary Jo's family over $100,000 not to have an autopsy performed, saying that it would prove they'd had sex and would ruin her reputation. Not a word about Teddy's reputation.....
Somehow, I don't think not getting to be president is payment enough for manslaughter at the least and murder at the most.
If he'd gone to the first house and called the cops chances are she would have died anyway. The only thing that would have saved her is if Kennedy had been sober enough to figure out how to get her out of the car or if there was a witness on shore that knew how to rescue someone from a car. Alternately, she could have broken out the window and saved herself...but most people don't know how to accomplish that.
That cannot be accomplished without the right tools (I have one on my keychain) and yes, a person can live for a long time in a airpocket, depending on it's size, the car wasn't completely sunk and his brothers even waded into the water to try and open the doors to get her out....chances are, had he gone to the first house to get help, she would have been saved, he was too worried about what it would to do his career to even think about it.
How could there have been an air pocket if Kennedy got out of the car? Wouldn't that have let all the water in to the car, on his exit?
Also, i am uncertain if cars had electric windows back then? Most car windows simply rolled up or down with a manual crank, didn't they?
