OK, I have once again cleaned this thread and warnings have been issued.
Lets keep it civil and on topic. Thanks.

There's a lesson in here somewhere - and TSA destroyed my drone

I think I need to build an underground bunker to store my kit in now, this hobby is starting to get expensive.
If you know the regs then you know a person can't check lipo batteries. You say, "don't even..." as if it were allowed.
You mention crashes. These involve hundreds of pounds of batteries. Thousands of batteries. The FAA has done testing on exploding batteries and for some reason they allow two spare lipo batteries in the passenger compartment.

Are we taking bets yet ?
Reports are saying engine fire but the pics I've seen look more like a cargo hold fire.

I've got exactly 2 cents this morning so here goes....
Has anyone actually put one of those "Fire-Proof" LiPo battery bags to the test?
I've seen YouTube videos but was wondering if anyone at this forum actually tested one.
I have a suspicion a lot of these bags on ebay etc wouldn't stop the flame from a match.
Also, even though the bag "might" prevent a fire, remember that if you have pets, they could still die from toxic fumes if one ignited (in a fireproof bag) while noone was home.
One other thought.....I use a battery charger that measures the batteries temperature while it's charging both internally AND externally. I have my charger programmed to shut down automatically if the temp rises above a specific temp. If you don't you might consider it.
I'll probably start storing my batteries in a fire-proof bag (sealed in an airtight bag) outside the house though after all this talk of LiPo fires. (Because I have pets especially).

They would know if it was an engine with all the modern sensors and such. From a passenger - He told CNN the plane was preparing for take-off when he heard a big thud. When he lifted the window blind he claims he saw "flames on the engine". My question is with the way these jets are maintained how could something like this happen?
When luggage gets inspected, they leave an inspection card inside so that you know it was inspected. Did you find this note inside?
I'm asking because the stock gimbal lock (at least on P3) is very easy to put on loosely and for it to fall out. It could be that the gimbal lock fell out and rattled around inside as the luggage was tossed around?
You are right about keeping a low profile.
Personally, I think those giant cases with drone logos are nothing but trouble. The invite attention from airline staff, customs, and thieves. It looks like you're carrying buckets of gold or very expensive electronics and that is not a good look to have.
Especially when traveling to developing countries, my goal is to look like a poor backpacker. Low profile is best profile.
You make it sound as if FAA/TSA/Airlines are some two bit operators no better than my local cabbie.
In fact, they've multi-billion dollar operations with highly trained employees. Any little rule is studied and analyzed and optimized by 100s of people.
They have studied the Lipo issued and they have issued Lipo guidelines. They are aware of the risks, and they have set the current standards according to this risks. (This is also why Inspire has 2 battery options.)
There's been at least one lipo fire on a passenger jet.
LiPO Fire onboard Fijian Airlines B737
All that said...people make mistakes and things happen. Otherwise there would never be plane crashes.
With all the volumes and volumes of airline regulations...people still die occasionally.

The jet probably injested a drone and the lipo started it on fire. Edit: Hidaven called it. I'm rethinking the safety of this hobby.
some quotes about DJI Batteries regarding battery fires
--------------------
But there’s one more solution, and DJI, creator of the popular DJI Phantom series of quadcopters, holds the patent to it.
Shortly after the launch of the original Phantom, developers with DJI wanted to ensure that consumers with less experience with soft pack batteries would be able to use them.
“We knew it would be a game changer because it further lowered the barrier for first time pilots interested in quads,” said DJI spokesperson Michael Perry.
Development on the Smart Battery for the Phantom II line of drones began in April 2013.
The Smart Battery’s are also LiPo batteries, with a capacity of 5200 mAh and voltage of 11.1 V. Power management is handled internally, meaning no balance connector is required to charge.
The one major criticism Phantom II users have? The price.
DJI smart batteries cost about $130, in comparison to the $20 LiPo batteries sold on DJI’s site (and often found cheaper on hobby sites).
“We cannot say for now if the price will drop. Part of the reason that the batteries are priced higher than normal LiPos is that all the smart features requires additional hardware (not just the LEDs, but circuitry), software and testing costs,” Perry said. “We feel that the intelligent features that people get out of these batteries corresponds fairly to the price differential with typical batteries.”
And that’s not to say that the DJI Smart Batteries are 100% foolproof.
“Heat is a big enemy of all Lithium battery chemistries, so even a DJI smart pack could be damaged by letting it sit inside a closed vehicle on a hot sunny day for instance,” Salt said. “Chances are it would never start on fire, but there is still some risk there – especially if it’s fully charged.”

Like Modzilla, I too use a military ammo box.Very heavy steel.
I also store at much less than 50%

Smartphones, Tablets, Laptops, Electric Shavers, etc. You name it. Everything today has a LiPo battery in it. They are all susceptible to catching fire and smoking etc. They all travel on airplanes probably many 10's of millions per day in the US.
Stop trying to scare people. Know the Airline's rules, usually no checked batteries and a limit of 2 for carry on and proceed.
Anyone know the potential for a LiPo to self ignite fully charged (or at storage charge) just sitting (hopefully rare)
vs
During charging? (Seems obvious it would be greater while charging or discharging)

A recall would be bad, too.Wonder what kind of battery is in my pacemaker .
It's reported (Goggled it ) 600,000 are implanted each year world wide
Boy thinking about self igniting ain't good for ya

600,000 pacemakers per year? That's a lot of testing, you be fine as frog hair.

Nah, ya got till the end of the month, cause thats when the world ends... again. - Is The World Going To End In September? Mormon Apocalypse 2015 Prediction Has People Stocking Up On Food

Well on a lighter note we won't have to worry about ....They gonna ruin the hobby for us all again
