Air France Plane Unfound; Most Likely Hit Lightning

[deafskeptic]

assuming that they're stranded on ocean. they're more likely to die in ocean than on land if it's been a week because

1. predator factor - shark, jellyfish, etc.
2. environmental factor - stormy weather, prolonged period of time under sun, salty seawater can causes diarrhea, dehydration, serious infection, hallucination, hypothermia, etc. much faster than you get those on land
3. health factor - no food, no water, no emergency kit... a simple cut on your head/arm/leg will be severely infected and worsened due to salty seawater, microorganisms, and poor health within just a matter of few days

Despite of these factors, it is still survivable for those with strong will and basic survival knowledge.

Provided they didn't die on impact and weren't so serverly injured they were unable to help themselves.
