Really interesting behind-the-scenes look recently from Aurora Flight Sciences — the subsidiary of Boeing with which Virgin Galactic recently partnered for two of its next-gen mothership design and tooling: https://www.aurora.aero/2022/10/05/behind-the-scenes-tooling-design-for-virgin-galactic-motherships/
Recall these motherships will each be able to handle up to 200 flights per year (so 400 total), with the first expected to enter service in 2025.
