Those seats don't look too supportive. Are these the seats they're in during take off etc? Check out what seats look like in race cars. They're still carbon fibre and minimal but have better support than those. That edge on the seat and no support for the head/neck or backs of the legs seem like it wouldn't be a very enjoyable experience. I'm sure I'm overlooking some obvious reasons why they were designed this way so I look forward to hearing more about this project.
