“Do I really need to do a buoyancy study...”
No, you weren’t talking about buoyancy (though that seems to be your favorite word today). You said:
Statistically the circumstances surrounding her death indicate a high probability of an unnatural demise.
Nothing about buoyancy there. So where are the statistics about how many out of shape older women dropped in the oceans after plane crashes survived? You have those statistics, right? You didn’t just make that up did you?
