If you jam any modern tablet in an airplane seat, bad things are going to happen.
You don't need to look far for reports of Samsung things catching on fire these days. In the wake of the Galaxy Note 7 recall, the media — and public consciousness — is highly sensitive to anything that looks remotely connected to the Note's unprecedented battery woes. That's true whether we're talking about a completely different phone with no known issues, or a Samsung washing machine made by a completely different division of the company.
In any case, here's today's exploding Samsung thing: what appears to be a Galaxy Tab of some description, which started smouldering on a Delta flight from Detroit to Amsterdam.
The flight was diverted to Manchester after smoke was discovered in the business class cabin, then the (utterly destroyed) tablet was found wedged in a seat. The talk of "overheating" and "thermal runaway" here might make you think the tablet's cracked appearance is unrelated to the apparent battery fire. But what's way, way more likely is that the battery ruptured because of extreme physical damage — the kind that'll result from jamming it in an airplane seat.
As Jerry Hildenbrand explains in an earlier article:
Lithium batteries are designed to be lightweight, deliver high output, and be easy to charge. This means that the outside shell and the barrier(s) separating the electrodes are very thin and light, with most of the weight coming from the parts that can actually power your phone.
Because the partitions and case are thin, they're fairly easy to puncture or tear. If the structure of the battery itself is damaged in a way that makes the electrodes touch, a short circuit will happen. The instant electrical discharge is explosive, which can (and will) heat the electrolyte and create pressure to push it out through any ruptures in the battery case. It's hot, it's flammable and it's in contact with a spark. That's a recipe for disaster.
A Samsung statement given to The Telegraph blamed "external factors" — it's easy to see why given the extreme nature of the damage.
Everyone is more aware of exploding gadgets following the Note 7 recall, and as a result, incidents like this are often reported in the context of other Samsung gadgets catching fire. Case in point: Reports on a Galaxy Note 2 catching fire over India last week.
What we have here is a case of frequency illusion. (Sometimes called the Baader-Meinhof phenomenon.) This is a cognitive bias — a trick of the mind — where something which has recently come to the personal or collective attention seems to appear with much greater frequency shortly afterwards.
That's amplified considerably by the modern media, which is quick to jump on unrelated stories like the Note 2 catching fire over India, and present them in the narrative of the Note 7 battery fiasco. Had the Note 7 not had battery issues, a story about a single smartphone malfunctioning (albeit spectacularly) on an airplane, with no harm coming to anyone, wouldn't have been splashed around major news outlets as much as it has been.
The very same applies to a tablet battery rupturing after being crushed in an airline seat. Would this be getting so much traction if we weren't in the midsts of an unprecedented smartphone recall? Probably not.
