Giving it another shot, Chief?
You really, really must be dense if you think computers have just now become capable of computing this sort of thing.... In my estimation a standard PC from 1985 with the most basic spreadsheet could have performed the necessary calculations-and even the cavemen back then knew this idea was B.S.
Before this magical computer and all its fancy-dancy NASA processors arrived, there were accountants who easily could have produced the necessary cost models-these people have been around far, far longer than the airplane.
-So, you really must be a complete retard if you are not smart enough to spot the error in your logic by now...
-Let me help you: Before the advent of flush toilets, no member of the human race ever took a dump-did they? Something starting to smell fishy in New Brunswick? Are you staring to see some parallels? Same exact logic you have used to try and impress us all here.
-Just follow that line of reasoning through, and maybe you will be able to see what a complete dumbass you look like.
