> Waterfall never worked for a reason

We're going to need some evidence for this claim. I feel like nearly 70 years of NASA has something to say about this.

While writing the comment, I did think to myself, that NASA did a ton of prototypes to de-risk. They simulated the landing as close as they could possibly make it, on earth. So, probably not pure waterfall either. Maybe my comment was a bit too brusque in that regard.
