Of course, I'm sure that any moment Elon Musk (PBUH) will be along to explain why the entire aviation industry was wrong to use these transmitters.
Was he wrong in his assessment of the original 787 battery overheating issue?
You realize that they still have no earthly idea what happened to the batteries involved in the earlier incidents, correct? The "fix," such as it is, simply involves the implementation of more robust containment measures.
Everything Elon (PBUH) declares is truth beyond question. Allow me to state that up-front so as to appease his followers.

And you realize you're replying to a comment which wasn't about the earlier incidents except insofar as it pointed out that this incident seems to be unrelated and really appears to just be an off-the-shelf component failing in a way that it could have failed on any of the other aircraft types it's deployed in?
My reference to Elon Musk (PBUH) was mostly because I'm already seeing in this thread the same sort of frankly religious worship of Elon (PBUH) we saw during the incidents which were unique to the 787, and I make a point of hammering on that whenever possible, since although Elon (PBUH) is a smart guy who does cool stuff, he's not quite at the divine-omniscience level seemingly attributed to him any time the 787 gets mentioned on HN.
A: Planes, Trains and Automobiles!
ELTs used to use NiCd batteries. I know there have been fire problems with ELT batteries on Cessnas and other GA aircraft in recent years. It sounds like the 787 was just doubly unlucky to be the commercial frame to get an ELT fire.

It's commonly used for items that will use very low-power for a very long time, with possible high-current pulses, which makes it great for alarms (it's also a common chemistry in "lifetime battery" smoke alarms, for example).
Larger lithium primary cells are a fire-risk (and are not permitted for passenger carry unless installed in a device).
So not the same batteries as the last time apparently. I wonder if they made the same "fireproof box enclosure" change to these batteries as they did the others. If these batteries were similarly isolated and still caused a fire that bad, that doesn't say very good things about the continued state of battery safety on those planes.
