My dad works in Aerospace (though admittedly more on the managerial side, but he still tries to stay technical), and he does all of his initial programming in Excel first, and then will port it over to Matlab if he needs something more code-like. I've been trying to get him to use Julia for that second step since I absolutely hate Matlab, but I honestly don't fault him for using Excel in the initial phase.
