^ I read in the aftermath of MH370 that developing a new airline passenger seat can run into $100Ks, because of how stringent the testing is. Not sure if amazing or ridiculous - suppose the two are not mutually exclusive!
Developing any complex mass-produced product is expensive, obviously more so if it's performance is highly regulated, but spread over 20,000 units (e.g. the Air France 777 fleet of 25 -200ER and 40 -300ER has up to 23,000 economy seats, depending on layout) $500k to develop a cattle-class seat is only $25 a seat, obviously much lower if you share a seat across airlines or aircraft types.
