This is a big deal since the need for windows is one of the reasons things like the Boeing Blended Wing Body has gone nowhere for decades, despite NASA's continued support of it in its own dedicated lab. More importantly, since radiation hardening is weak around windows, and since they're expensive and interrupt the cheap wet filament wound shell best used for both aircraft and spacecraft, you want to avoid them. I've been expecting this for more than a decade and they're saying it is still a decade away, but not if we start building commercial spacecraft sooner.
