Concerning the recent crash one of the TV commentators said that it

and not warm. the reason he said is that cold water is *harder* than

water and made for better ditching conditions.

Any truth to this.

No - cold water is less dense than warm water.

That's why ice floats.

I guess that's why the plane is floating. 8)

This is really strange. You answered my post and my post hasn't even
appeared on my news service (Giga News)yet. I made the post 65 minutes
ago.

Can you tell me what time stamp in on my original post. Thanks

Giganews is screwing up. I'm seeing the same odd behavior.
Still haven't seen you original post.
I heard that guy too, and thought he was full of it.
Cold water is more dense than warmer water, which is why it sinks.
You've heard of thermoclines. I've even felt it wading in the ocean.
I don't think it makes a difference in landing a plane on it though.
Ice is an expanded state of water. Takes of more space than liquid
water. That's why it floats.
But ice is harder than water. At least I think it is when I fall and
my ass lands on it. Doesn't hurt when I fall the same distance into
the water.
Diamonds are real hard, and are forever.
BTW, I'm not a scientist.

Water expands as it becomes colder.

You can't have expansion in a liquid without it becoming less dense.

It's why ice floats.

Wait - let me check on something.

Erm....sorry - I'm right, but I'm wrong at the same time. I forgot
one little minor detail.

Water expands at the freezing point - otherwise, it acts just like
other liquids. Water does become denser as it approaches the freezing
point.

Water temp in the Hudson was 41 degrees F which is almost at the point
of freezing.

So the newsguy was right, although I doubt that made much of a
difference.

But so what if you get hypothermia?

Bottom line, get out alive.


It is a US Airways flight. They going to reimburse all those $15-25 checked
bag charges?


No, they'll say the bags arrived at their destination.
