"ALSO EVERY AIRPORT SHOULD HAVE MOCK EMERGENCY AIRPLANE DOORS FOR PEOPLE TO TRY OUT."
I would pay money for this in the safety amusement park, but in real life way more people would get hurt operating the fake one at the airport than we'd help in real emergencies. Plane crashes where the emergency exit gets operated are so rare they effectively don't happen.
I had the opportunity to deploy (and use!) a slide at a Lufthansa event, super cool experience but given that just the slide deployment probably cost them over $30k I can’t really see it being a common thing.
Of course just opening an exit door replica you could do for ~free
