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

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.

Methinks you are wrong. Ice floats on water. The process of freezing is
a strange one.
First it contracts, then it expands and breaks water pipes.

I suppose this is sort of boating related.... sigh.

As water gets colder it gets denser. However as it approaches freezing the
way the water molecules start crystalizing results in a less dense solid.
There are very few things that behave this way and water is one of them. It
is a good thing to otherwise the bottom of the ocean and big lakes would be
frozen forever.
