Of course. Even the Space Shuttles blew up, twice. I'm guessing even pace makers and software in nuclear power plants have bugs. The point is, these things are exceedingly rare or have very limited scope (occur only in most obscure corner cases and also do limited damage), while in web companies which adopted Continuous Deployment, serious bugs are just common and I think seen as part of life.
Work in healthcare where we have heavily tested, quarterly releases. Well, we had a release today and some stuff was pretty horribly broken, despite being so heavily tested. We didn't adequately load test one piece of the new release under production-like conditions. Oops. Thankfully the fix was simple and a hotfix only took a couple of hours in total. Yet another lesson learned.
That's pretty bad, but nonetheless you detected and fixed it very quickly. Compare that to lingering bugs in Twitter iOS client (it's just broken on iPhone 5s, I guess they simply don't test on that device anymore), or happy random bugs in Windows 10 that appear after they CD an update on their users.
