Yeah, no. In EU+CH alone, you've got Schuko, French, reversed French (Czech), British (Ireland, Malta, Cyprus), and more rarely Italian, Danish and Swiss plugs. And those are just the current national standards as of 2026, ignoring anything non-standard or historic or foreign.

You can't just slap some ungrounded 240V Frankenstein multi-socket on the back of a plane seat and call it a day. Hell, you can't even do that in your own house in most developed countries.

That's before you even get to passengers plugging in their own $2 socket converters off eBay, half-inserted and loosely hanging off your already-lethal socket. And then these passengers wrap themselves in a synthetic blanket and go to sleep. What could go wrong.

We're not talking about some CRUD web app here, where being held together by sticky tape and prayer is fine and expected. This would actually kill people. Not exactly easy to deal with a smouldering corpse in the middle seat at 30,000 feet.
