Right...but what I was getting at, is that the chemical mixture of lithium polymer batteries is no more volatile than the lithium Ion counterparts that we use every day from shavers, to laptops, auto's, and beyond...its not something that is just going to explode or go to thermal runaway state without being provoked to do so; i.e. just sitting in a storage bin.
Not exactly true. There have been reports of um-provoked combustion.

If major brand manufacturers of laptops and automobiles have issues as they have, it is no myth. I personally have had a LiPo battery with no previous history of damage short in flight. I was flying along one evening right before dark and noticed the battery glowing at the corner of the pack. It was mounted to a flying wing where I could see the battery.

Great vid...they said that the cause of the Sony Battery fires was a manufacturing flaw in the battery. Also, I would note that not one time did it say what the specific cause for the fires was; battery charge circuitry failure? Battery Charge level circuitry Failure? I doubt it was strictly the "chemistry" that caused the fires. If they were that unstable, we couldnt use them. But this video also proves my point that LIPO's are no more or less hazardous than "IONS", and even the smallest of cells can start fires, but yet we dont throw our laptops in fire proof cases, do we?

I don't see how that video proves your point in any way, shape, or form. I'll take a LiIon over a LiPo for safety anytime. If LiPos were as safe why are all the Laptop manufacturers still using LiIon instead of LiPo?

No, no proof at all. In fact, more evidence that safety is taken much more seriously and the incident rate is very low. Look at the figures for cell phones. 339???
And that gets a reaction. That's 339 out of how many? It also doesn't say how big a fire they caused. I can show you lipos that burned down cars, houses and whole fields. I personally know at least 3 people who had fires. I don't know anyone who has experienced a fire with consumer electronics. And I know a whole lot more people with those than with RC lipos. The difference is clearly astounding.
They also mentioned a number of pics of burned laptops...dozens. That is a very low number compared to how many are out there. And they didn't say how many houses burned down. I think the plane that crashed near Dubi was caused by cell phone batteries...80000 of them! That's a pretty big battery if you look in detail.
And, the point of li-ion being more volitile may be true but is a mute point. Because of their better packaging and other safety measures implimented, they have a MUCH lower rate of safety issues than RC lipos. Look at the whole picture not just one little point. I feel much more confident with my laptop than my RC packs...and I treat them accordingly.

But, forget all that. Just answer the question above. What do you suggest to prevent a crashed heli or plane from starting a fire?

+1! I've been using a Laptop for work on a daily basis for nearly 13 years. I've carried this thing in/out of a a major city in my backpack, on the train, subway, on the airlines, etc. It's never been babied, it's my work machine. I've had 4 different ones over that 13 years. Thankfully I've never had a fire. But I certainly trust it much more than I do any of my RC LiPos.

Then what the hell did we just watch?! Those werent LIPOS, they were IONS. Your not even listening to what I'm saying...and yet you post up a video that shows all the ION fires, but yet continue to defend that they are the utmost safe? I'm going to defend my point that LIPOS are no more or less safe than Ions, with regard to the way they are treated. I'm not even going to bother answering your question, as if a Laptop loaded with a lithium ION battery pack would pose any less hazard than a LIPO being smashed into the ground at a high rate of speed.
