Innovations in Flying and Elsewhere

This was a Business Class like no other I have been in. Individual seats that can go horizontal. Was on this flight where I got upgraded, and looks like it was the right one to get upgraded on! Comfortable, so that even the half-hour delay circling over Mumbai did not seem like much (on a one and half- hour flight). Why don't they make all seats in an aircraft like these? Isn't that what innovation is supposed to do?

Anyway, let's leave that to high-flying innovators and concentrate on our job. What have we innovated lately?
