The re-entry issue isn't unique to Starliner - there seems to have been a significant risk of the Apollo 11 re-entry from the service module. ... 8040787cbd
I thought I knew quite a lot about the Apollo missions, but have to admit to not having come across that before! Fascinating.

From there I followed a link to the story of Sergei Korolev whose rockets brought humanity above the bonds of Earth's gravity, including his modified R-7 which launched Yuri Gagarin into space: the first human to break the gravitational bonds of Earth, building on the work of others such as Konstantin Tsiolkovsky who were at work on the problem long before humanity ever broke the gravitational bonds of Earth.

Now it's bad enough that the author got fixated on "gravitational bonds" but in a low earth orbit the gravity is almost as strong as at the surface (maybe only about 10% less); orbits only happen at all because you're "bonded" by gravity.

I'd have expected better from a "Ph.D. astrophysicist, author, and science communicator".
molto tricky
