Most of these rules are from the 1970's. That's why they have to show you how to put on the dadgum seatbelt. Hello, it's been law that every car has to come with a seatbelt for how many years now? It just goes on and on... us frequent fliers have heard the script many times. It reminds me of Dr. Sheldon Cooper on "Big Bang Theory" with his geiger counter, emergency bag, evacuation plans with a quarterly practice LOL. It's a funny show but this is pretty stupid in real life. The vast vast majority of flights arrive with no need for any of the emergency evacuation equipment or the flight attendants. Ever been on a Beechcraft 1900? There is no flight attendant. The pilot does a shorter version of the safety briefing, and upon arrival, opens the door so you can leave. It's not hard! Granted, in flight, the cabin employees could be salesman, hawking drinks, snacks, guided tours, etc. (like Allegiant Airlines), or they could be surly and hand out complimentary drinks or just sit there and do crossword puzzles. All this stuff like you have to have one F/A per 50 passengers (except 19 or less hence the B1900), one door per 110 passengers, be able to evacuate the plane in 90 seconds, can't store anything on the floor under your legs, exit row briefing, life preservers, rafts, blah blah blah, all this stuff is from the 1970's! Have you noticed that since the 70's, planes rarely crash? And when they do crash, everyone gets killed! What's the point of all this emergency evacuation if it doesn't happen? It's just a big waste of money. How much of our ticket costs are for this? I'm guessing 20%.
