And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Now, why wouldn't there be racer style seats there? It is the space shuttle, after all.
Also recall that the seats need to be sturdy enough to withstand the G-forces of launch. Once in orbit, a seat cushion would be unnecessary. Weightless environment.
Why no super-duper seat? Because until Elon Musk came along and decided to build a spaceship out of steel, all previous space vessels have all been under the 'must cut weight' rule.
Only with Orion (bomb pushed huge spaceship) was weight ever not going to be a problem. Well, even Orion had a weight issue, as too little weight would have been a problem. No, seriously, true.
I read a whole book about the seat design. They were not just about saving weight, there were a bunch of considerations. For one, thing, crew needed to be able to ingress and egress the seats wearing a pressurized suit. Also, the seat would be used in vertical launch as well as horizontal landing, where the occupant would be subject to very different stresses. Hard landings needed to be accounted for as well. The seats also had the ability to be removed and stowed, as most would not be needed in orbit, and to allow access to panels below them. They also have to accommodate inertial reel and oxygen systems. The commander and pilots seats have both electric and manual position controls on the Z or X axis. They are not budget seats.
Those are Spaceship Seats which has to be way beyond racers seats!!

ReplyDeletethe astronaut suits they wear while taking off and landing make standard seats useless.
