Re: 4 blade vs 8 blade C130H

Any been near the H model with the 8 blade props vs the old 4 blades? Is there is a noticeable decibel difference? Collins Aerospace claims its NP2000 eight-bladed propellers reduce noise by 50% (20 decibels) compared with the old 4-bladed propellers. https://www.collinsaerospace.com/-/media/projec...

Re: What happens to ISS if Russia backs out.

Actually Starliner is built to be launcher-agnostic, it can fly on F9 just as easily as Atlas or Vulcan. Whereas Crew Dragon is vertically integrated and can only fly on F9. That said, it's unlikely there would be a need for either to fly on the other's launcher, unless there is a grounding issue. ...
