ThinkTaker - have a read of "command and control"
It's a factual account of the Damascus Titan whoopsie ( and no disrespect to the dead, they were the poor brave bastards at the bottom)
In the book you will read an awful lot about the numbers and the close calls
And you are advocating going from the most reliable system we have ever had to a less reliable one - and I use reliable here in the sense of less likely to have a whoopsie
