Planes fall from the sky far less than, say, some agile/scrum-based web app shitting itself constantly, which happens all the time. Maybe waterfall has its place.
Eh. Waterfall adds risk to iterative approaches, not value. Wait 3 years to do integration testing because that’s what the schedule says. The smart projects get better quality and use iterative models.
Additionally, there are other iterative models than Scrum. That's pretty much the worst one out there and its only value is to inexperienced teams needing training wheels or overbearing management that doesn't trust the team.
